This may be a really stupid question, but is there anything to do with your bikes when you're out and about with it on your bike rack? I have a trunk mounted bike rack. My trails are 1/2 hr away from my house so it's not easy to just run over there and I always have errands to do, but my bike is on the back of my car! I've ran into stores real quick but it would be so easy to steal if someone knows what they're doing. I put my bike lock on it to make it look like it's secured to someone who doesn't realize that they can just take the bike rack off! Any suggestions on what anyone does? Thanks, Danielle
