Does anyone know how the car share in Denver works?

I've never done it, but from what I understand it's pretty straightforward. The program I'm aware of is called eGo CarShare (www.carshare.org). They have cars parked in various locations around the city, often near transit stations. If you're a member, they give you a car fob. You can reserve a car, and they set it up so that your fob will work for that car. When you're done you return it to the same place. Pretty cool system if you don't drive a lot and you live near one of their locations.

Sure! I think it's kind of fascinating. In some ways I'd like to live that way myself, but I don't see it working for a real estate agent :)
