Wow weldngod I've missed you
Anyways this is becoming more and more common and will only get worse. I've seen this in many places and have been posted on the forum a few times.
Doesn't it suck. We call them the (fun police) come out not having any clue of the actual law or what the rules actually are. They greet you with alot of authority basically wrecking your fun cause they have a job or position that empowers them to tell people what they can an cannot do while they can't conceive what it is your actually doing. Most go right to safety concerns others feel as if its their property they don't own and is being threatened by some new cult takeover.
I'm up against the fence on this one. Part of me says screw them the other part of me says be responsible and think about other future kiters and respect the wishes.
In your case it sounds as if its public land that is soley your home to kiting that is different than the soccer mom problems we face here. Its easy to get torked off but be careful what you do or say to the authorities
The good ol days are over and it may be time to take a more in depth look at the laws and rules of where you are kiting.
Whats the rules there?
Who owns the land?
Find out as much info as you can before going back. Come prepared and make them eat their own crap.
The only true way to win this game is to play the game. Its time consuming and can cause undesired stress but if you believe in it you may start a new kiting spot that is safe from this kind of stuff.
For example this is a much larger issue but in this issue of hang/paragliding magazine. A fly site was in jeopardy in a town that I really enjoy flying over. The airport and the hang gliders got into a pissing match over stupid stuff and ended up shutting it down. Well they pleaded and brought everyones attention to the matter and really watched and rehearsed what to say to the officials and WON. Basically F$%k you airport we were here first and your flight path sucks choose another approach that is less dangerous anyways. They also got the landowners blessing and the forest service.
You won't end up in that kinda spotlight I hope but take it easy drink a beer and lets figure out what we can do

I love the wind and I love getting HIGH on air.
