It's just a ride with 700 of your closest friends.
That's good info about the wind- thanks! That may help me decide between shorts and knickers too. The last forecast I saw was for high 60s and partly sunny.

As for the cassette change, I'll probably mindlessly change it in front of the TV some night this week- no big deal. My recent experiences with uber-flat riding were in the C&D Canal area, and I remember feeling like I couldn't find the right cog to keep a steady cadence.
