And this is how the hobby gets it's undesirable reputation... It's still privately own property. I walk by a few homes everyday, look like nobody lives there, most of the year... Somebody's vacation home, used maybe once a year.
Eventually foreclosed homes get sold, or at least people come out to look at them, what happens then?
We aren't the only type of treasure hunters either, who look at these types of properties, for personal profits. Scrap metal prices go high, some get a little crazy on where the acquire the !!!!. They aren't doing their hobby an favors either... I would want to be the guy, hunting a bank owned home, that had been gutted for scrap metal.
Guess for some people, knowing it's risky, and getting away with it, adds enjoyment and excitement to the adventure. Coming up with a good line, and talking your way out of a sticky situation proves your smart and clever. Wonder how much fun it is, when a neighbor calls in suspicious behavior...
