Not your typical KOA from the moment you drive-in .... they have gas pumps! I have never seen that at a KOA. Comparative prices from what I’ve seen and other gas stations. I used-the showers here I must say that was an interesting shower. It’s a push button and the water will run for about 20 seconds . I guess it’s their way of conserving water you can’t faulted them for that. I’ve always had a good experience at KOA’s and this one is no different very well-maintained and the employees were very friendly.

Stop over...not your typical KOA. Large, big rig friendly. Not many campers so we had a lot of privacy, level lot, great places to walk your dog. Clean. Did not use any of the facilities. Would like to return for longer time.
