The only problem you will likely have is that the High School Football season is already starting to wrap up in many places. I suspect most places will still be in the playoffs when you arrive, so you can probably find a game somewhere, but it will be more limited than if you were here in Sept. or Oct.

There isn't a good place to find a national schedule, but if you search for "High School Association"and the state name, you'll probably find a schedule. Otherwise, be looking at the local newspapers which are usually good about putting out schedules.

I'd suggest that you try to get to a college game, but it looks like you've already got plans for the Saturday that you'll be on the road.
