... those were covered in the "etc." part.
Sand bags work best if you can put them over the drive wheels like weightless pickups. Front drive cars, not so good as you're putting the weight in the back which lightens the frontend. Have a friend sit on the hood instead.

You can also spread the sand on ice to get more traction. A carpeted floor mat works in a pinch to get out of a snow bank.
Studs are good on icey intersections. Steel wears out too quick for me but some higher end tires offer titaniaum studs that last 2 or 3 seasons, according to a friend of mine. Never seen one fly off a tire and they're a bear to get out physically. Had to do that years ago when I couldn't afford summer tires and the fine for each stud was like $15 if caught running them in summer. It's only $50/vehicle now.
You should be amazed you AMC still runs. I'm amazed they still make parts for it. Now where did all those Yugos go?!
