I would like to know how you protect your bikes. One rider told me that a disc lock is only used to slow down my bike from being stolen. Or you apply the rule "don't leave it without your sight"? I had a gut feeling that 3 strange guys were talking or thinking of borrowing my bike on Sunday at my mom's apartment. I'm going to Las Vegas on Thnxgiving for 1 nite and have to leave my bike at a parking lot for more than 12 hours out of sight. Wish me luck & many thanx.
