EHorn, as a good engineering student, I know you can do a cost/benefit analysis. Once you add up the gas, food and hotel from the road trip, plus the hours of your time that you could be partying at OSU instead of driving through Missouri, I think you'll see that big ol' jet airliner makes a whole lot of sense. Priceline.com is your friend.
I do the drive down to Houston from Columbus every year for a car meet, and I'll tell you -- if there was any other way to get my car down there, I'd do it. The drive just sucks. I was going to drive down to the Alamo Bowl, but some sense got knocked into me at the last minute and I flew.
Either way, enjoy your stay in our fine city and enjoy the game (just not too much ). I'll be down in Austin for the return game in '06 and I'm flying!
