When we used to go camping, my dad used to pick and fry up wild mushrooms. Thankfully he never had any trouble. He had learned the skill as a boy growing up in Poland. I never had any desire to learn the skill though.
As a youth I lived in NE Pennsylvania, amongst the Eastern Europeans. The only thing that would clear out the schools quicker than Deer hunting season, was the cry of, "Pipinkis are on the mountain!"
