Sorry but this is almost unforgivable. I hope these individuals are never allowed back.
And airplanes crash too.
Remember the TSA is the rule police. They don't make the rules. If they don't understand or get confused they say no
So, I speak from a little point of knowledge here. I've spent more that a couple tens of thousand$ at horse shows in Pebble Beach. After 40+ years, PB decided to shut down their horse showing there and the 2 partners that ran it split. One went north the SAC, they other up the coast slightly.
Here's what you need to do. Explain to the pilots who this group is and that they will someday soon be fighting these people for their right to fly their planes.
Horses are NOT compatible with planes either.
The pilots and auto crossers should be on the same side. Pilots deal with noise issues all the time.
State owned profitable park. Going to be tough to shutdown..
I think making sure the pilots know the threat is the answer. The runway incidents need to be solved and that's why they don't like you - no pilot wants to have to dodge something on the ground - planes don't work good there
Been there - done that
The FAA does listen to pilots.
