+1 that is the drill. That is why I mentioned the cost of stealth camping. You are often not camping in a nice place, though it might be, and you only leave the road when it is dusk, nobody is going to spot the track off the road, because it is asphalt, and the birds around here are small, and tucked in already. As much as I agree with the idea owners know their land, I am still thinking that if the SAS had a hit on, and were surveiling your house for a few days before the main force arrived, you would probably not know it.
Also, there is no guarantee the camping is in the country, the best places are often around towns. People seem to think they need 1000 roam-able acres, no, they need a comfortable safe place that is not frequented by people. Those are abundant in town. Plus if you are sociable, you can pick a spot, then do your shopping, drinking, movie watching, touristing, and dive in when it is dark. Less mosquitoes. Anyway, when country people (I also own a lakeside farm) start paying their way in tax, they can complain for real about city people and their vacations, not that I notice much complaining around here. And some of the choice land is owned by people who only come a few weeks a year. Basically, there aren't any nasties, around here other than bears.
