Not too many retired guys (in their 60's and above) have time for computers. Any guys that do use them had access while still in workforce. A true "Bum" would not want to own a computer, he would rather have a new Sage. Let alone spend time on one.

The Midwest Salmoniod fishing is way too new to produce a true PNW bum. Give us a few hundred years. We are all too busy working as your life as mine is devoted to bringing home the cabbage.
