Does the track ever get “rained out”?

Just muddy, but has covered areas to stand

The off-road track looked pretty well designed as far as over all grade/drainage, but I'm sure there are a couple of areas rain water might pool up a bit. Probably wouldn't take long for it to dry up. The on-road track wouldn't hold any water; it's asphalt and raised slightly above the surrounding land.

Do you mean does it close? No, it just gets muddy. Its open 24/7
