no, no, no, a "supposed" city ban like that never includes a person's OWN property. If it was true, it's for city property. You can hunt your own property till you're blue in the face. I sometimes hear about supposed city wide "bans", but my guess is, they start like this. True story:
When I first got into this hobby, the guy who got me hooked made a comment one day, that "all the parks and schools at such & such city (30 minutes from us) were off-limits, and you can get busted." Who was I to doubt him, since I was the newbie? So naturally, I passed this info on, as if it was fact. Afterall, who was I to question this? Years later, we started deteting a certain park in that town, because a 3rd party was getting some nice silver out of it. We were never bothered, but it was always in my mind that I had to look over my shoulder and be careful or something. Eventually, I ran back into that old friend, and asked him where he got his information. He said that one day he was out in a school yard there years earlier, and got booted by a janitor. When he asked "why?" the janitor said "it's not allowed here". When my friend asked "well what about the other schools?", the janitor said "ALL public property". My friend just tucked his tail and left. Now OBVIOUSLY, this was just a janitor having a bad day, or just an isolated incident (for all I know, my friend was leaving holes or trying to do it during school hours or whatever). He should have just treated it as an isolated incident, and just avoided just that one school or person. But instead, he takes what he is told as if it is fact. A rumor is born that "such & such city is off-limits".
Just my opinion, but nowadys, 30 yrs. later, when I hear of such & such, or such & such city being "off-limits", I wonder if .... in those locales .... if anyone really even cares? I mean, sure, if you waltz into city hall with a shovel in your hand, OF COURSE they'll say no. But if you're discreet & leave no marks, my hunch is you'll not be bothered at parks and schools.
