I'm mostly familiar with some of the D III VA schools I have visited over my son's travel ball the years.
Randolph Macon has a very nice field and fun game atmosphere.
Christopher Newport has a really nice design. The fence used to be very weathered but still a very nice place to play.
Mary Washington had a nice small stadium feel to it.
Hamden-Sydney was a very nice field and small stadium feel.
Washington and Lee was top notch as well.
I'm not sure if any of these schools had indoor facilities that would be nice to have in the Virginia Spring climate. But they were all really nice places to play or watch a game. Most of the Virginia D III schools have very nice fields for the fans and players. We are probably very lucky compared to many locations.
