Where's some good places to get rider's autographs? did they have certain stations set up for teams to sign before or after the races?

This is my first time so I'd like to get pictures and autographs and stuff.

My plan is to watch the first riders start and then work my way to Coit tower and watch the favorites finish up the big hills to the tower. Hopefully my wife and daughter will be up for the walk. hehe!

Then maybe next year I can volunteer!

Thanks!
Gary
