Most AAA schools take baseball seriously, most A do not.
Larger urban areas embrace competitive summer baseball ie. elite travel teams, USSSA, AAU etc.
Most small towns are still stuck with Little League and Dixie Youth baseball. Do you see a correlation?
In urban areas where competitive summer ball is played, the parents are serious about baseball. In small towns where Little League and Dixie Youth are played, parents consider baseball a recreational activity. If parents take summer baseball seriously, they will support and push for a high quality HS program. If parents see summer baseball as a recreational activity, that's how they will view their HS program.
