I fly on weekends at a nearby high school. I'd fly during the week (evenings) if I could, but rarely am I off work in time.
I didn't get permission. I figure it's public property paid for by my tax money, so using it during non-school hours is fine. Besides, since when do "underpaid, overworked" school officials take their off days to patrol their campus grounds?
Not gonna happen.
As for getting us kicked off public property...it won't happen unless (1) a serious accident occurs and provokes retaliation by the local public; or (2) someone with a lot of clout and a good lawyer decides we don't belong. Without probable cause, it's too much effort for them to find a way to get rid of r/c flyers.
Of course, slimers are much more likely to arouse trouble. So, if the slimers are doing okay, you know our electrics will be just short of being invited to fly!
Am I right?...
