We live in HOA community, and recently local security start chasing parent/kids, for "unsupervised" kids on property.
They already had some legal problem trying to restrict access to one of swimming pool for kids, and now this thing.
1. We have swimming pool behind the gate.
2. We have club house with written notice <Parent supervision required> for kids.
3. And we have a lot of play area green.

For all of this list rules could be different, I think.

I've checked everywhere I could and looks like it's not legal, this is property, I feel save on it, and I let my 8 year old child go outside, who is right or not, local board of dirs are really don't care about kids, they are all retired and they made them sick I think.
