Clay,
I have a T-Shirt but no hat. When we went to the Kool April Nights car show here last year, there was a Gas Hole booth there. No relation to the club. But boy, did they want to know how I got that T-Shirt. I told them we were a club that ate a lot of beans and chili.
Also, most are very friendly. Heck, Turk would even introduce you to women that he didn't know.
