It's Josh here for one final blog. I am sitting in Knoxville airport and still in shock that it is over. Everyone seemed to be happy to see their families. I will never forgot this trip as long as I live, and the people who went on it were incredible. I hope everyone else enjoyed having me as I enjoyed being with them. Thanks to everyone who helped with anything. Most important thanks to Casey Cobb who undoubtedly lost countless nights of sleep worrying about a trip that turned out to be a hundred times better then I could imagine.
