I Like Abus Hardened Chain locks . they have a cover like a nylon hose.

Or look for something really heavy , lock stays on the rack ..

tell campus security , and agree on a code* label,

so if they want you to move the lock they will call and ask you rather than just grind it off.

*Code rather than actual personal info.


I moved away from a college Or hip Bike town , theft potential reduced as a result.
