I'm going off to college and have a 2006 Giant Yukon. I know that an mountian bike might look expensive sitting on a campus bike rack and that bike theft is rampant on college campuses, plus it's in Atlanta. I was wondering what is the best way to 100% secure that bike to a rack. I'm willing to cover the bike in chains if necessary. I hear that using several U-locks and a chain might work, but I would like to know what you all use to secure your hogs down.
