But you wouldn't have known it -- 3000 3-Day walkers and 350 crew members, and boatloads of cheering fans made the city of Philadelphia warm as a tropical beach.
I may have had better days, but I'm hard pressed to think of one that's more meaningful or inspiring.
This photo is of the closing ceremony -- after all of the walkers and crew have entered the ceremony site, the survivors enter, and everyone holds up a shoe in tribute.
More to say about the experience in days to come, 'cause I'm drop-dead tired right now, but suffice to say that it was a spectacular event and I think I'm hooked. See you in 2010!
