Did you guys all park together, some goldwings, and some harleys, and a jap racer ? If they are the bikes I'm thinking of, then yeah, you were dusty. Woulda been good to know you were going through Dover, you passed about 100 feet from my house (Across the highway from KMart).
The toilet on the kart was cute, but I liked "Pastor Pauls Private Potty" with the porta-john in the back of an S-10.
I'm thinkin of a spring loaded sling-shot device mounted on a sled on a track, also spring loaded. As the sled shoots up the track, the release pin is pulled which releases the spring loaded sling-shot. Sort of a double whammy. I don't know where they would classify it, catapault ? Just something else to add to my list of projects.
