Yes, we've all heard that the pen is mightier than the U-lock... Thanks, Kryptonite, for your lock-exchange service, but what about U-locks manufactured by other companies? I have an old (circa 1996) Rhode Gear Gorilla ATB lock (with a round key), and I'd like to know if I can exchange it. Anyone got any ideas? I'm a lowly writer on a budget, so I'm hoping to avoid the ol' "just get your butt to REI for a replacement lock, lady" comment. Thanks!
