The person overtaking is responsible for overtaking safely.

I ride on multi use trails, as well as in traffic. Every time, and I mean EVERY time I pass someone, be it on a bike, roller blades, or walking, they get a "DING" from my bell, or if they are wearing earphones, a friendly but firm "On your left!"

When I'm on the road, however, I use my air horn... Yes, I have an air horn on my bike. Best thing EVER! You use your bike pump to pressurize a bottle that sits in one of your water bottle cages, and there is a small tube that runs up to the actual horn on the bars. You press a button, and an ear piercing shriek comes out of the horn. One pressurization of the tank will be good for a good 30 second long blast, but many many more "normal" length toots.

This is similar to what I have. It even has a volume control of sorts. (It's a valve that limits the amount of air admitted to the horn, so you can mash the button, but it won't be ear splittingly loud, in case you want to use it to give people friendly "toot toots" on the trail.

It isn't that a smaller sensor magnifies the image more. It's that the smaller sensor is capturing and resolving a smaller section of the entire image projected by the lens. This is a good illustration of it. Say the entire circle is the image projected by the lens. The black square would be the 5D's full frame sensor, while the red square is the 7D's crop sensor. It isn't magnifying the image, it's just capturing a smaller portion of the projected image as a whole. It creates the illusion of more magnification, when in reality, it's just resolving a smaller portion of the projected image as a whole.

The concept of a divergent lens between the lens and the camera's sensor is illustrated by teleconverters. I shoot Canon, so I'm going to stick with their equipment for my examples. Canon makes a 1.4x teleconverter, and a 2x teleconverter for their cameras. These apply a multiplicative factor to compatible lenses (usually Canon's L series lenses). So, with a 2x teleconverter, a 300mm lens on a full frame sensor would become a 600mm lens. Unfortunately, these teleconverters reduce a lenses' widest possible aperture. The 1.4x reduces the maximum aperture by 1.5 stops, and the 2x reduces maximum aperture by 2 stops. This becomes really limiting in anything but very bright light, because realistically, your minimum shutter speed should be the reciprocal of your focal length in order to eliminate camera shake. So, if you're using a 600mm lens, you should be shooting at at least 1/600. So, let's expand on this. This is the longest lens I own. It's a 300mm f/4 L, compatible with my 2x teleconverter. With the teleconverter, it becomes a 600mm f/8 lens, on a full frame camera. So, without taking image stabilization into consideration, your minimum settings will be 1/600 at f/8. ISO, or sensor sensitivity, can certainly make up for this. However, it's also important to understand that adding this teleconverter has added distortion, and is degrading overall image quality. Additionally, most modern cameras can only autofocus with a lens that has a widest aperture of f/5.6 or lower. Off the top of my head, the only exception to this that I know of is Canon's 1D-X, their flagship model. So, it isn't that it's impossible to generate fairly long focal lengths on a moderate budget, but image quality and overall capability are going to suffer from doing so. Canon's longest lens that is under $10,000 is the 400mm f/5.6 L. There are versions of the 300mm and 400mm lenses with wider maximum apertures, but those are also extremely expensive. So yes, overall, this is very possible, but to do it effectively, it would be extremely expensive.


As for the idea of adding a close up filter, those don't really magnify an image too much. They really just magnify it in such a way that a plane of critical focus can be achieved at less distance than you would usually be able to achieve it with a lens. Additionally, they add a considerable amount of distortion and degradation of image quality. This is something to consider any time you add an element between the photographic subject and the sensor itself. Every layer of glass will degrade image quality to a certain extent. Some lenses are made and treated in such a way that it reduces image quality significantly less than others. Again though, glass that nice is usually pretty expensive.

I've never tried it and my dad always shudders when i ask him what it tastes like, but, according to the The L.L. Cookbook, bear is really good. I've also heard that the fat is good for cooking and making soap. Either way, it's something I'd like to try one day.

The G1W is pretty much the standard consumer dashcam that is not super expensive, fairly reliable, and films in HD.

I have used one for 2 years now and, other then having to reformat the sd card one time, have had no issues. Turns on and off along with the car, can record for over 8 hours with a 32GB SD card (make sure it's class 10). Over all I have been happy with it. Just make sure you aren't getting some weird knockoff.

Outliers is a great book. everyone should read it.

Twist of the Wrist, a must read for anyone wanting to learn how to ride better.

Something like this probably

Immersion blender. Like this.

Ouch, he's going to need one of these at the very least.

Accirding to this bookyour death is most likely to be from internal injuries, so you should position yourself flat on the floor of the elevator. The authors did an AMA

This is infomercial level stupid/lazy - he needs a pick stick

...and this is why you always use a line dampener.

I keep one by my desk: http://www.amazon.com/dp/B001R1RXUG

There's a book about that!

I highly recommend The Complete Far Side. It's a bit pricey but holy crap. I thought I was a Far Side connoisseur and then I got it. I'd say at least half of the cartoons I'd never seen.

i also heard the earplugs are kinda high tech (if that's what you'd call it) because they block out loud noises like gunfire, etc. and let quiet noises like talking come through. but i also heard they don't wear them anyway because they're annoying and don't work that well.

edit: link to earplugs

this ass book is cheaper

We avoid all thoughts of death in the west. We just don’t want to think about our loved ones or ourselves dying. That’s why we let funeral services deal with the whole thing and you pay them the big bucks.

A really great book by Ask a Mortician lets you get comfortable with the idea that you’re going to die and everyone around you is going to die and there’s nothing you can do about it, Smoke Gets in Your Eyes
