Other NFS fees....
Like Iowa Dave, we have encountered the upcharge for electric at some NFS campgrounds, well worth it and still a bargain. One time we also got charged a $3 fee for our dog at Horsethief Lake NFS campground near Mt Rushmore. That really surprised us when we drove in, had made reservations months in advance, then were told we had an additional fee when we hadnít encountered that before in all of our many years of NFS, BLM, and COE camping. We havenít had one since, either-wonder if the ďhostsĒ were running a little side gig....😉. If so, they made a killing off all of us with pets!
