In addition to the non-availability of trucks, I'm also a bit bothered by lack of distributed pickup locations. In Los Angeles, you can only pick up Zipcars at either USC or UCLA (or within a couple of blocks of those campuses), which makes me resist using the service for as long as possible. Nevertheless, I have used the service twice and have been pleased with the results both times. So, good when I use it, but I would use it more if it were better (are you reading this, Zipcar??)
Anyway, I wanted to share with you how I make it work: I have to ride my bike up to UCLA, then stuff it in the back of the car and drive it away. I guess I could also park the bike nearby... but I would spend the entire day worried about whether or not it would be there when I got back. So behold, Ruby getting a ride in a Honda Insight:
For the rest of you who are car-free, how often do you find yourself borrowing or renting a car/truck?
