Trailer? We don't need no stinkin' trailer!
Last week, I took a 6 day motorcycle trip to the Smoky Mountains. On Saturday, I rode my motorcycle in five different states all in one day: North Carolina, Tennessee, Kentucky, Ohio, and Indiana.
I think that's the most states I've been in in a single day on a motor cycle. Oh, and on the 7th day, I rested.

(Who says milestones have to be BOINC related, right?)
