It is, but it takes a lot of time to dig through prospective areas a couple hundred yards at a time hours on end. And what really sucks is I can’t find the time or money to do ground research at the sites I find. So I reach out to local entities who might be interested to go check them out. And of course they get the credit for the find. But I don’t mind, it is like hunting for treasure. The satisfaction is just knowing you did actually find something important. :)
