check out bikes that are worth slightly more than yours... and get locks worth slightly more than theirs.
or, hell... just go crazy. get an NYFU, an STD-3000 and a bikeregistry chain with the upgrade lock. with a bike that's worth $250, on a campus with expensive bikes that are poorly locked with cheap locks, just about anything other than a dollar-store lock should work.
on most campuses, you'll see bikes that are "locked" through a quick-release wheel, usually parked next to another bike with an unsecured wheel that's compatible. and bikes "locked" around the seat-post, through the front fork, etc.
good locks are nice, but so many bikes get stolen because they're just locked up wrong.
Two campers are walking through the forest when they suddenly encounter a grizzly bear.
The bear rears up on his hind legs and lets out a terrifying roar.
Both campers are frozen in their tracks.
The first camper whispers, "I'm sure glad I wore my running shoes today."
"It doesn't matter what kind of shoes you're wearing, you're not gonna outrun that bear," replies the second.
"I don't have to outrun the bear, I just have to outrun YOU," he answers.
when locking a bike on campus, you don't have to outrun the bear
