They have bleachers, but the field sits in a valley. There is a hill that many people sit on behind home plate to watch the games. There is room along the fence line for chairs, as well.
Also, they allow people to sit by their cars in the outfield to watch the games. When they held the districts there 2 years ago, they did have a person at that gate to charge admission.
It is a rolling outfield and slightly elevates towards the fence.
