I needed a place to stay for the night and stumbled on Blue Mesa Recreational Ranch in Gunnison, CO. Very lucky for me I noticed in the office it was a member park in one of the other discount camping clubs which had just become re-affiliated with my Coast to Coast group. They had no problem with me just showing up without a reservation and happily provided me a nice space cheap for the night.
The campground is built on a hillside overlooking a lake. My site was still level and the tiered spaces let everyone have a great view of the lake which is very popular for boating and fishing. The park has one outdoor pool and one indoor pool with a hot tub. There is a hall to gather in and eat. They do have wifi. I wish I had more time to stay there. Will definitely have to go back some time.
