One not to do.
So there are some great ideas here. But here is one NOT to do. Now Please remember we were only 16 and city boys. So there are four of us and my buddy takes his moms new 69 Chev Nova to Big Bear for a overnight snow trip. We get up in the morning and windshield is frozen, we try to scrap it with a knife we found in our rented motel room. One of the guys said I have got the fix. He goes in the kitchen turns on the hot water and fills a pan. He comes out and throws it on the windshield to melt the ice. I am guessing you know what happens. CCCCRRRRACCCCKKK...... Oh shit.
So parents warn your kids if they take your car to the snow. You city people that is.
You're never lost as long as you still have gas!
