When I suggested in a thread that a certain show where they were using shovels and pitch forks on public property was giving a black eye to our hobby, I was called a "Troll" and told that nobody likes being told what to do. By that same logic I might then say to those people that this guy has the same attitude, that he doesn't want to be told what to do either.
With freedom comes responsibility. If we don't police ourselves then there are plenty of people in the government that would just love to do it for us. That above article is just one example of bad behaviour in our hobby. More common than tresspassers like this is the bad reputation we are getting by guys who are too lazy to bend down and dig a hole. Keep taking those long handled diggers and miltary shovels onto public lands and see how fast those places are closed down.
These youtube videos and TV shows where they are (I hope) hunting on private land showing them using shovels and other long handled diggers doesn't help our public image either. They need to make it a point to say that they are only using those because they are on private property and have permission, and that they would never use such digging tools on public property.
The biggest problem in this hobby is a lack of common sense. People using offensive (in the public's eye) digging tools, guys who go to the beach or park when it is full of people and hunt right around others, people too lazy to do a good job filling a hole or picking up their trash, and so on. What about these guys who go around and hunt the tree lawns in front of houses without asking permission? The city may own that property but that isn't going to stop the home owner from calling the cops on you, and the next thing you know their city park is also now off limits.
I'm sure that guy in PA had the same attitude..."Nobody tells me what to do." Hey, I don't care for the government telling me what to do either, but that's why we have to police ourselves and use some common sense so that we don't attract unwanted attention to ourselves. You have no "right" to metal detect in the government's eyes.
