"When you're stupid, you're stupid for a lonnnnng time"
Years and years ago I went to a friends house to help him burn his field. He thought tossing tuna fish cans of gas to spread the fire while holding a gallon gas can in his other hand was a smart thing to do. He said "I'm real careful to make sure the liquid is disconnected from the tuna can before it hits the flames". I told him he was forgetting about the fumes and I was leaving if he didn't stop, that I wasn't going to watch a friend get burned. He started setting the gallon can aside, but he did let me leave. Before I was out of his yard he came to me with singed arms, apologized, and ya know, here it is 20 years later & he still mentions how I saved his life.
Kerosene, OK, gasoline, NO!
Staying on subject.... it takes way more heat than you think to melt snow. Just shovel it.
