yeah I can tell you most of the stuff from what I know from the 4 years I've gone, assuming it's still all the same. The show is at the Dayton Airport Hotel parking lot. There is normally about 500 cars each year with a swap meet also.
Friday is mainly registration and people cleaning their cars at their hotel and talking.
Saturday there is more registration and the actual show goes on, cars are judged Sat afternoon. Also on Sat there is an all pontiac drag event at a dragstrip somewhere outside Dayton, don't remember the name but I think it was a really weird name. Saturday night is a cruise in into downtown Tipp City. The streets are blocked and only Firebirds/trans ams are allowed in. The cruise in is free and the show is free to see but they charge for parking but it's a donation. Also on Saturday they normally have some sort of a seminar with someone big who specializes with Pontiacs. One year it was a GMHTP writer another I think it was the guy who ran the prototype stuff with Pontiac. It's always something pretty interesting. With the editor he talked about how dyno rating really work and things that you could get easy horsepower from and such.
Sunday is more show and the awards ceremony is aroun 4 I think normally. Nothing real special goes on Sunday normally.
Overall the show is awesome and there's always something to do. Everything is normally pretty well planned out.
