Yep, I can tell. The Charlie Fox I mentioned, is probably in his mid-70s, still active in PA hunting/fishing affairs and fairly well-known in these parts. May well be two of them?
I believe Don Lewis was in his late 80s when he passed away last summer. He had given up the Shooter's Corner column in the PA Game News a few years ago, but still did occasional shooting/hunting articles for one of the Pittsburgh-area papers.
