I haven't heard about pre-games sales and I work in the school system.
I think Appo has pretty decent parking. If the big lot at the front of the school is used there is a fair amount of parking. I've been to places that are much worse I know.
Schedule wise Appo has played some bigger, tougher schools so far. They lost to a good Heritage team who is doing well in the Seminole and beat Rustburg. Now Rustburg record wise is not that great but they play in the Seminole district which is very tough. (Heritage, Jefferson Forest, EC Glass, Brookville, Amherst, and a few others)
Bottom line is this game could go either way and if mistakes are made could get ugly for wither team. I will say Gretna is the favorite in my opinion. They are returning a talent squad and have lots of speed. Appomattox is still growing and this team, while still dangerous, will be much better down the road.
