Awesome park near Dayton and Palouse Falls. Absolutely NOTHING, including cell service nearby, which made this open campground in a winter wheat field absolutely perfect!
The hosts/owners are good people, who are accommodating, and welcoming. Will definitely be back and enjoyed the gem.
Side note unrelated to park.... ran into the mother of all dust storms about 40 miles west of here near Othello and ended up posting up in Connelly. Added a day to the trip but was a sight to behold. Wow!!
