This is absolutely correct...according to Nancy Heltman, the DRC person in charge of the dog rule, the sole purpose of the pet fees is to discourage campers and cabin occupants from bringing their dogs. I have had numerous personal and email conversations with Ms. Heltman on a number of subjects (including site specific reservations, which I think you will see soon) and she is adamant that pet rule serves one purpose...to discourage campers bringing their dogs. I camp host in VA state parks fours months each year. Most campers are good about cleaning up after their dog, keeping them on a leash, and keeping them quiet. There are always one or two that need reminding but 99% of the dog poop I clean up comes from MY dog. I dislike the dog fees and will continue to lobby against them as long as I can.
Just saw online today that Virginia is keeping it's current reservation system of non-specific sites.
