Paying to camp on public land???
5 m car
With the remote location, with no mobile data (only call and text). So, a couple hours prior to arrival, I texted the temporary Hipcamp number provided, which sends the hostess a message in her Hipcamp app. I provided my number and asked the hostess to directly contact me via phone instead.
Upon leaving the paved road, we followed the written directions previously provided by the hostess. They were very detailed, but told us to turn down certain road names...which turned out to be unmarked. We texted again for help, and the hostess again neglected our requests. The anticipated 45 minute dirt road trip, turned into 2 hours of almost non-stop driving around lost.
Some Good Samaritans on an ATV were our heroes. They helped us find a different camp site only a few minutes away, and notified us that Ferguson (aka "Fergie") Ridge (where our directions were taking us) was public land, along with the new camp site. According to them, camping at both locations is free to anyone, and NO ONE SHOULD BE CHARGING ANYONE TO STAY THERE. Days later, when I had mobile data, I verified the public ownership on Mariposa County's tax GIS mapping website.
In summary, the hostess did give us a refund, but only after sending us on a wild goose chase, not responding to our cries for help in real time, did respond hours later via the app chat (which was unhelpful because of lack of data), and did so under the (evidently) false pretenses that she owned the place and has the right to rent it to campers.
