The theory of bike locking (per Sheldon Brown), is U-lock your frame and back wheel to the stationary object (which you have to make sure is stationary, some street sign posts have bolts that are easily removed; and wood like on your deck can be easily broken). This is why a larger/longer U-lock is often necessary. Then a cable can be run from the U-lock through the front wheel.
[Edit] Alternatively for more protection, a second U-lock can lock the front wheel to the frame at the down tube, then the cable can run from either lock through the stays on the saddle to prevent saddle theft.
Ultimately every lock can be broken, the goal is to deter and slow down potential thefts.
I use one of the longer OnGuard U-locks. Hasn't been a problem, yet!
