Had a 5-8 cook off in my shirt pocket 1 evening about dark, muzzy hunting in Scott county 1 cold ass day and dropped my 2 way radio in my pocket, forgot about the MC, bouncing down the trail on the atv with my buddy setting on the back, bang, thought I had been shot but no pain, my 2 way radio was a drop in charge model and the charging points heated them up enuff to cook them off. Got lucky learn by my mistakes lol
