Gem State is a Gem
Nestled in the small town of Mountain Home, Idaho, it's a great park for overnight or longer. There are a couple of drawbacks, but the amenities outweigh any. First: Being located in town, there is some traffic noise on weekday mornings as the neighborhoods surrounding the park heads out to work. Our wood picnic table has seen plenty of use and should be updated to more modern models before too long. There are some other questions in the back of my mind but I don't know the park that well yet to comment.
Now for the amenities: We pulled in on a Sunday and the office was closed. There is a 'host' that met us as we arrived. Robin greeted us, led us to our site and got our utilities ready for use. He brought our paperwork to the site, pointed out the facilities, and was genuinely friendly and personable. The office building has restrooms inside with shower facilities and is very clean. There is a laundry room available. The sites are hard-packed dirt or similar, and long (accomodating large RVs). They're spacious and shaded. Not good for solar, but not needed as shore power is available. We were able to set up our small dog pen and still have plenty of room for outdoor lounging. My RV is a 40' 5th Wheel.
