lol... if your gonna do that in vinyl, thats gonna be alot of work, and if you go to have a place that has a graphic plotter, thats gonna run a little bit of cash. I used to own a sign company remember,lol..
Best bet would be to keep it simple.black vinyl on white canvas. Maybe some orage and yellow to make the logo in front. We just need something to tell people hey were here!!! Then again If you jot down the cars that will be there....... lol as if that combination of cars will be found anywhere else. lol. Not like theres all that many GG Si's running around.
speaking of Cops... You gonna bring your screen tent again jeff? lmao. Just get the thing up and they make you take it down. rofl.
