I just hunt them, never had a problem with anyone.
Wow, you're going to get "roasted" now dholland. Tsk Tsk.
Seriously now, if I understand what dholland is getting at, is this (if I can disect it please):
a) on the one hand: yes: churches are private property. No one would debate that.
b) however, notice the TYPE of "private property" it is. For example: SO TOO are shopping centers "private property". right? Yet none of us would think we need permission to waltz around a shopping center. Or to do something odd like whistle dixie, etc... In other words, yes it's private property, but it's more on the order of "permission to pass revokable by owner", or something to that effect.
c) So unlike someone who comes into your home, churches and something like a shopping center are thought of differently. Heck, in fact, they WANT you go to that church, that shopping center, etc... right?
d) Yes I know there's lots of flaws in this, and someone is sure to point out that merely walking there, attending there, etc.... is different than "digging holes" Yes, I grant that. But just trying to say, there are varying types of private property when you think of it.
When I was a Jr. High kid, our school bus picked up the neighborhood kids at the curb adjoining a Baptist church. Ie.: sort of at the end of a gravel parking lot. The kids would line up, to board the bus everyday. This was one of those sort of lawns or properties, where ..... there's really no demarkation of where the sidewalk ends, and the lawn starts. The lot and/or turf just sort of extends all the way to the street's edge-type-of-thing.
So when I got my first detector, as a kid, and wondered "where do I take it?", I thought of our bus stop as a logical place. Since .... afterall, kids had done the same as I was then-presently doing, since the earlier 1960s at least. So off I went and "helped myself" to this area. As I finished working our immediate loading zone, it was only natural to continue to wander further and further, till.... I was probably on the lawn of the church itself. Closer to the front doors than the street now

But what did I know, I was just a dumb kid, haha. I got several silver coins and wheaties out of that church yard as I recall, and never thought anything about it. I even recall a janitor coming out one day and asking what I was doing. He just shrugged his shoulders, and walked back in. In retrospect, I'm sure... yes ... he could have booted me (or worse), but alas, these were the innocent 1970s, and I was a pimple faced little kid on his new toy. how cute, eh?
But in all that time, even though, I instinctively knew not to go on someone's "front yard", as that just .... seemed different. But for some reason, churches just seemed different. After my success (of a few silvers) on that yard, I wised up and thought "gee, this should work the same for churches all over my town". So I hopped on my Schwinn Stingray bike, propped the detector on the handlebars, and off I went! Never for a second thought that this was somehow wrong or disallowed. I recall being booted from only a single one (which perhaps is when I began to realize, "wait a second, ... hmmmm ... and re-think it). haha
