I just checked Google Maps and it absolutely takes you to the spot that we stayed at, I'm not sure why it labeled it the Sweetwater County School District, haha
You can trust your GPS along this route, at least as far as the site we stayed is concerned. We have a large fifth wheel and had no trouble accessing it. There seemed to be several other spots nearby so if you have a smaller rig you can explore more. Windy, but we loved it!
