Bicycle Combination Cable Lock
At Burning Man, you will want a combination lock for your bike because most likely, you will lose your key dancing in the middle of nowhere... The walk back can be very long and lonely (oh, I wouldn't count on friends sacrificing their bikes to walk with you...). But you may forget the numbers? Nah. Code it 111 or 123 or 222 - something easy to remember. The lock is not to protect your bike from thieves. It's to "help" confused individuals understand your bike is not theirs. People accidentally take the wrong bike all the time. This lock acts as pure hinderance to avoid the "borrowing" your bike (until they realize it's not theirs, which is usually 24 hours later).
