I really don't think driving across the state for a state Championship game is a big deal. These are generally once in a lifetime things for most families, unless your Maryville or Alcoa or Ensworth.
ETSU has indoor stadium? Right?
GHSA was done by GA Public TV as well. But the production was a different level. It was night and day. Sideline reporters, half time coverage, etc. They even brought in HS Goal Post.
GHSA probably has a bigger budget. If the games were just shown in HD that would be enough for me.
