Ditto to what Shefly says.
It is hard to find pics when you dont' use the number on helmet, but usually they have a sign of what film roll it is.
They also give you a number to put on bike. I usually do not attach it. You can wait to attach it when you have to put your bike in the "bike corral" for over night or the truck for transport bike. It flaps in the wind--and will drive you crazy. (Well it bothers me)
At the ride in Texas they had this large cardboard-ish number to attach to the front of your bike. There was a 20 mph head wind and folks have this large cardboad number to add to the drag. And if a cross wind it hit it, there when you handlebars turning!

It was VERY cold for the over night when I did the "GreatMass" a few years ago. As for the ferry boat ride. I wanted a nice quiet scenic ride. IT was a BIG party boat! It was like at a wedding reception...people that never get out and drink and dance have gone wild!

Oh, still take snacks. On day one, the lunch provider (sandwiches/subs) FORGOT and we had cape cod potato chips--yum, but not substance.

Then when we got ot the finish on day one teh beer line was MUCH shorter than the food line....must I say more!
I did have a great time!
