That is a great idea. I was just talking to Todd Sommer about making up a tee shirt as well. There was a "BBQ Injected" shirt made by a Dieseler that was an excellent artist. I'll do some checking and see what we can come up with.
Here is a business card I made up awhile back. Musta been quite awhile, the post office won't deliver to the PO box anymore :)
I am not an artist by anymeans how about a diesel scout infront of another car (or a jeep) and making them eat its smoke. SSmmmokin' Scouts Club with the scout guy with a big grin and the car(jeep) people getting aphixiated. Tony
