Ouch. Had a similar experience a couple months back. I made a smoke pouch for the grill. When it was spent, I took it out and sat it in the snow beside the grill. When I went out to grab the food about 20 mins later, the smoke pouch had melted through the snow and was smoldering on the decking. Needless to say, I have a deck board to replace this summer when it stops snowing.
