We were meeting cousins from Texas to do the Lewis and Clark loop (the campground is an excellent choice for that) this past weekend (August 19-21). The heat index was 120F. No lie. The campground had nothing to do with the ambient heat, but as there are only a couple lots with trees, very little grass, and the spaces are narrow enough to hand your neighbor a stick of butter from your window to theirs, we were all pretty miserable. 

On the high side, the laundry and restrooms are above par (and the air conditioning was excellent), they have a lovely pool, and a small but adequate dog run. The cheese shop is very well appointed and included some lovely local wines which was a life saver as it was too hot to cook. Wine is a major food group, right?? The hosts were friendly and the facilities very clean. The park is right on the highway and so if you're looking for white noise...you've got that going for you. 30 amp power, sewer, and adequate water pressure at the site was nice. We were in space #68...I'm not kidding when I say they're narrow. 

Not a place to recreate, but definitely a safe and clean space to spend the night enroute to your destination.
