For the past two days, I've been driving...

I recently won an auction for a mustang -- a gorgeous strawberry roan we're calling Aesop Rye. I spent all of Wednesday towing all 1,000 pounds of him, plus the 3,500-pound trailer.

The trip was grueling, and we made plenty of pit stops along the way. But surprisingly, one of the things that didn't bother us as much was the price of gas.

In Milwaukee, Wis., gas prices are running between $3.60 and $4. The farther south we went, the cheaper gas prices got. In Oklahoma City, just north of where we picked up Aesop, gas was going for $3.23 -- more than 10% cheaper!
