It is upsetting to see this but I will say, if they were offered for free for the taking I have to give them credit. There's an amusement place out by me that WILL NOT UNDER ANY CIRCUMSTANCES LET ANYONE HAVE STUFF FROM THEIR GARBAGE. I put that all in caps because it's been yelled at me so many times it's the only way I can remember it. When I used to work near there, I snagged 2 complete Tron cabs, Carnival, Choplifter, a couple random empty cabs and a ton of parts. When they found out, they started destroying them with a sledge before they put them outside.
So yes, it happens but at least they offered them (and still offer them) for free before doing so. I'll give them props for that.
