Amen.
Park Flyers don't bother me in the slightest, have at it, I say. The more the merrier.
I fly jets and scale and all sorts of junk, but the last thing on my mind is getting shot down by some guy in a park. I worry more about getting shot down by my fellow club members making a goof.

I flew for YEARS at local parks and schoolyards, still do now and then, and the chances of someone being nearby on your frequency are just so astronimically against it...
It's just a non-issue. Except for guys who think they have "real" models and you don't.
