Every year, lots of folks ask me who made the posters and T-shirts; Jason Cope @ Start the Press has designed and printed all posters and T-s since the second year.
The link to his print shop is here
By the Way, every year there are only 20 or so custom posters made, none for sale, however,there are 3 ways to get one:
A) win the race
B) score one from the Bike shops and coffee shops
(if they let you have it that is) but please wait until the day of the race to take it down.
C) Sponsor the race
