I called and was told $35.
This is an unmanned RV park at the fairgrounds. It is located in a rather seedy neighborhood with nobody around. We felt very uncomfortable here so we only stayed one night.
We stayed here for several weeks while visiting family. Basically a large gravel parking lot with full hook ups. Proximity to town and services is good. I would stay here again.
We've stayed here several times off and on since going full time in February. While it is next to a trailer park that doesn't look the greatest, and while we have seen homeless-looking people digging through the dumpsters, we've never felt unsafe. Just keep things locked up and you'll be fine.
It's not fancy but we had a full hook up with 50 amp service. All gravel parking. Next to park is huge Grassy fields to walk dogs or walk yourself. Area isn't Belair but I didn't feel unsafe. It's a great place to stay if you need to hang your hat overnight or a weekend.
