This looks like fun!
Here's my first contribution - I convinced Andy to take the Polar Plunge in my place after my boss signed me up. I remember Dan did this at some point, although I think there was actually snow in those pictures. Anyway, I covered the Plunge for the paper, so here are links to the story and to the photo gallery. The pic below (which is also on my Facebook profile) is me and Andy and Andy's younger brother Mikel.
