St. Louis to Columbus Carpool?

This is sort of a pre- and post- show event. :)

I'm driving to Columbus from St. Louis on Wed. June 25 and leaving on the 29th (or possibly the 30th).  I have some open seats and would like to help cover the cost of gas.  My rig gets 30mpg on the highway.  I have 3 open seats in a Scion Xb, though it could get tight with luggage...

A little bit about me:

I run the website for Armchair General magazine (a mag dedicated to military history and interactive historical fiction) and I'm going for business mainly.  Long time board gamer, wargamer, and sci-fi fan.
