Hi all,
Just wanted to share with you a website I found. They ship cars across the US and Canada. The cool part is that anyone can sign up to drive them. You pay for gas. Bad news is that it's a one way trip (unless you find another car that's going where you want to go). I'm sure there's also a time restriction or something like that to prevent you from going from Seattle to Detroit via Florida.

Disclaimer: I don't work for the company. Know anybody who works for the company or even anybody who has done any business with them. It just seems like a cool thing to do.
