I believe this was in 1986. My roommate, Shannon, was heavily involved in Boffers, a Live Action Role Playing System (LARPS) and as his parents had a hundred acres to play on, he hosted a few games.
Jon, Jo, and Mark set off on their adventure.
The adventurers approach something cautiously. Who, or what is it?
It's the Shannon Troll. Wait, troll?????
Run away!
