I have not seen a 5 yr old rule either. I have seen plenty of 10 year old rules. When I called the CG operators said either send a picture or bring it in to be inspected. A very nice place I inquired about had the 10 year rule and the nightly camp ground was $60. I was also told that I would need to double bag my dogs "solid waste" too
. She did say I could send a picture
. The campgroung was a very nice one with all the amenities but there was one in the same area for $40 a night with everything but concrete pads.
