2 questions: 1) Is there a paid dump station there? 2) if there is one available, how late in the season is it open?

Yes. You can pull in and dump for $10. Not sure how late in the season they are open. Thinking Columbus Day.

Josh probably knows more than us, we were traveling through. No idea about limited season. Their website should give that info, or call them.

There is full hookup sites, with paid rental. Dont know if you can pay to dump without staying there.
