California banned drone flying in local and state parks, so there are precious few wide open spots to fly without taking a 20+ minute drive. There are however, a couple of schools near me with large fields. Obviously, I would only fly when school is out, I've done it on the weekends when it's completely empty and it was quite pleasant. I might work up the courage to fly maybe 2-3 hours after school is over (and no organized use of the field, maybe a few stragglers, at most), but I want to ask to see first, if there are any regulations I'm not aware of regarding that. And secondly, what your experiences have been with that? Is that generally a good/bad idea?
