Someone mention /6 drag racing?
I am sure Monster Mopar will have a shirt but I'm thinking a /6 specific shirt. Maybe it should have SlantSix.org, 20th anniversary, FABO, etc on it somewhere. My favorite Mopar event of all time was the once in a lifetime Hemi reunion at Quaker City about 7-8 years ago. I'm not Joe-T-shirt guy but that one's a favorite. They ran out so were taking orders and mailed them a couple weeks later. I rolled in with my 68 cuda and the fools waved me inside to park on the field like my driver was anything special...not!
