it's just not out on the brush you need a car kit.over in St Paul Mn a couple 70+ years old ladies were stuck in their car for about four hours only a few miles from home.they called for a tow but with a ice storm underway no one showed up.a city sanding truck stopped,they were on a ice covered hill,and said they would send help.nope,nothing.a second sander came hours later and the women and some people behind they finely got moving.i don't carry much in my "city" car thinking a cell phone and blanket should be enough but i'm going to add more including a heater of some sort and a couple bags of sand.
