Green, Green Park
This is one of my favorite parks to stop in. They have a couple dozen spots, all long and easy to pull an RV in to. There is a dump station in the center of the park too, in case you are just passing by and need that. Be aware that half the spots in the summer time are taken up by the Habitat for Humanity crew - we think that's cool. Wi-fi is excellent, people are super friendly.
The park itself is surrounded by baseball fields, golf course, football stadium, rodeo grounds. All convenient in one location. - Grass is always green, check it out, right on the edge of town.
