I never actually broke down out in the hills, but got stuck many times. Flagging down passing people in trucks or jeeps is often a good way to get help getting pulled out, but mostly I had to do it myself. Lots of shovelling mud and snow, digging out and piling rocks and logs under the wheels, jacking up with bottle jacks, stacks of wood, hi-lift jacks, tow chains, come-a-long winches, all were useful at one time or another. Little wimpy folding shovels are pretty patheic when you get seriously stuck, theres no replacement for a full size long handled round point shovel.
Stuck my 1960 Willys pickup in crusted snow once, I started digging out, with a pathetic army folding shovel, stopped when i got 3 feet below the tires and it was still snow. Put the snow back. Used salvaged boards id found at a camp spot to drive on to get out, 4 feet at a time. Think that was about an 8 hr adventure.
I guess I had a dead battery once when tipi camping with friends about 30 miles out on dirt roads. B and I hiked several miles to a fire watch tower and talked to the lady there, she was super busy relaying active fire info to the hotshot crews, but said one busload of hotshots would be coming back along a nearby road soon, so B and I hustled out and caught them. They gave us a jump. Cool! Driving back to town, about a third of the way, huge thunderstorm coming in from the west.....I stupidly said "Well, about the only thing that could stop us now is a flat, I dont have a spare"...I seriously no sooner said it than we heard air hissing out of a tire. Pulled over, took the unmounted good spare tire and spare rim with bad tire, Max and I caught a ride to town while her hubby and B jacked up the truck and get the dead tire off, we rode in with some turkey hunters in the back of their truck. Got the tire mounted at the tire store, hunter guys drove as the 20 miles back out, slammed the wheel on as the first drops of the storm start falling heavily, jumped in the truck...then the rain came hard!
There are good people in the world.
