I am kinda beyond trying to convince anyone in authority or supposed authority that my rig fits their criteria. They may see the light but vary rarely do they just make the call to let it go. That said....I have never been told to take down my rig but I try to follow the rules of the area I am in.
I'll go home and write a letter to their superior or the governing state. Let it be know that I will choose NOT to camp and pay their fees.....hit them in the pocket. We the public can choose where we want to go and spend our time and/or $$. It is a bit piddely but in time it may change.
Thanks for taking this on.
