Very few, if any, places I trap have cell coverage. My home doesn't have any. I don't own a cell phone. My wife has an old one from the kids she keeps in her car for when we travel.
I do have a satellite phone. It has come in handy a couple of times.
I have a few things in my truck in case of a bind. They include: duct tape, flagging tape, vise grips, screw driver, good knife, a couple of Silky saws, fire starters, lighters, tire iron, 4 foot jack, tow rope, shovel, usually an axe, booster cables, granola bar or three and juice packs, socks, gloves, tuque, fly dope, paper towels, and fuses for the truck. In the fall I put the winch on for trapping season. If it will be windy, I might have a chainsaw with its gear.
A couple of years ago i got the truck stuck after crossing a stream. The right front tire was of the ground and the ass of the truck was sliding off the road towards a marsh. It was really close to tipping and rolling. I was able to tie the front end and use the cell phone to call my wife. She came with the winch and I got out easily. Since then, the winch goes on prior to the season.
