First Wax Castle parade I saw was 2002, the main grandstand was then at the intersection of the Police Box. Years later it was moved up near the gas station, with a waiting line not at the pump.
If you want to see performances then find a seat close near one of three grandstands and come early. Most likely there will be a live broadcasts.
I was privileged enough twice to sit in the main grandstand
