UPDATE - This is no longer an option when traveling through Craig Colorado. Due to complaints from the KOA campground in town, the fairground does not allow overnight camping unless you are traveling with horses, or an event is actually taking place there. I got this information by calling the fairground office at 970-824-5708 and talking to the nice gentleman who answered the phone. Too bad, because there was a pretty park there with grass and trees. It would have been a pleasant place to stay for an evening, but we lacked a horse! We camped here in a Fifth Wheel.
The county in Craig, CO has put in RV sites at the fairgrounds. All trailers park on level asphalt along the fence with hookups. The county built a beautiful shower house that is kept spotless. What a relief from the high priced KOA in the area. I wish more cities and counties would do this. We camped here in a Tent Trailer.
