Forest Service Campground - First Come, First Serve & hosts

Pitch and Profdant both bring up excellent situations.
Pitch, don't feel "but" or "bad". I absolutely hate when double dipping happens on campsites. The All American Greed Factor.

We always try to put the tag etc. in a baggie just in case. Also, we don't have the problem because our fiver is sitting in the site, but always recommend to tent campers, van dwellers etc. always let something sit on the site and make sure your occupancy tag is where it is supposed to be.
