Are you using a tent? Or, an enclosed trailer-type vehicle? Or, RV?

The reason I ask is that PacRwy management don't seem to  mind you using an RV or trailer, but there's not really anywhere that's comfortable to put up a tent. That one area beside the children's playground is OK, but if it rains it gets awful wet.

A tent on the pavement could be cold and damp. Get as "high" up the paddock as you can to avoid the water running down.
