Always position a U-lock so that the keyway is facing down towards the ground. Don't position the lock close to the ground. This makes it more difficult for a thief to attack it.
The Kryptonite lock tips are mostly sound, but this one (#6) caught my eye. Especially the third sentence. It obviously applies to the first, but if you read it in the context immediately after the second, then Kryptonite are advocating we should be doing all we can to help the thief!
