When I do the yearly trip to camp, I take a little hand held solitare game that I can turn the sound off on. We have 80 acres with three or four of us, so its hard to get down and walk around on those slow days. I have to admit though, the game doesnt get played often.
I too am busy watching the squirrels, grouse, foxes, etc. And the rare elephant footed mice that frequent the area too!
