I know it is a long way up here, but this KOA is a premier spot. The park is big, well laid out concrete sites, all pull-thrus, picnic tables, 2 dog yards and well manicured. In addition a big casino and plenty of places to EAT. In the past Don has ventured up over the border into Oklahoma.
I am not sure of the rally rate or rally hall usage, but the rally room is big and really nice. Right now the Red River Rovers from FMCA are here.
Might be a good spot to look into for a nice long rally and to venture out farther.
