I have a guy that I work with who does T-Shirts and says that he can make some for us cost is about 15$. If there is any one who is interested let me know. We also need to come up with a desine for it. I was thinking www.washintonriders.com on the back across the shoulder and a pic of some type of sport bike on the back. I am no good at the artist thing. The you can have any color you want as long as you like black. Other colors are about 1 extra. If you are interested post up.
