I can understand if you're dropping your bike off somewhere, or if you're going a fair distance with a lot of stuff, but otherwise, just ride the damn thing.

For instance, I plan on hauling my bike about 150 miles away this summer...but I'm also bringing 120 lbs of dogs, enough clothes to get me through 6 weeks worth of summer camp, two aquariums and a stereo. If I could figure out how to haul ALL of that stuff on a bike and not want to kill myself on the smallest of hills, I would; however, there's a reason for those technological advancements. I figure that since I use my car 50 miles a month or less, I'm entitled to use it when I need to.
