When I was in the navy, my friend and I used to go to Lake Geneva. If we had known he lived there, we might have stalked him, as we wasted out senior year playing D&D.
I went to a church youth thing in Fort Worden, Washington way back about '79 or'80, and they were playing D&D as a sponsored get to know everyone activity. Playing that at an old army fort is a cool place to play it!
