<p>The U-lock is a good idea. And always lock it to a bike rack, through the wheel and frame. If you do that, you should be okay (especially if the bicycle isn’t too expensive). There are literally thousands of bicycles on campus. Some aren’t locked up very well (including some fairly nice bicycles). Here’s how I see it: as long as your bike is locked up more securely than the ones surrounding it, and it isn’t worth considerably more than the ones around it, nobody is going to mess with it.</p>
