CruiseAmerica tells me it'd be about $180 ea w/ 5 guys, about $150 apiece for 7. Plus gas. That's for 4 nights, estimated mileage included. It's about 700 miles (12 hours) one way from my doorstep. Obviously that goes up if we don't cram it up to capacity, which I'd be inclined not to do anyway.
With any luck, I'll be a free man by then. We'll get some kegs of homebrew, a few mason jars full of completely legal, taxed liquor, and ride the Carpetbagger Express clear down to South-By-God-Caroline! Let's do this thing!
