I guess I should plan ahead a little more, because I wanted to see what it would cost to rent a convertible over the July 4th weekend, but there aren't any available.

I couldn't have packed much if I rented a convertible anyway.
Here's a deal: Too bad I'm not in Florida wanting to get to Chicago. They're offering a one way rental from any location in Florida to Chicago for $1 per day. Anyone in Florida looking to visit Chicago?
