Yeah, us Jeep drivers take some sort of wierd pleasure in pulling people out of mud/snow/whatever. I'm pretty sure it's some sort of genetic defect.

If you haven't alrealy got one, I'd suggest an actual tow strap as opposed to a rope or chain (you can get them at Walmart.) The other vehicle has to overcome the resistance of the snow/mud that you're stuck in plus the weight of your car, and might be pulling it uphill if you go into a ditch. Ropes tend to break at very inopportune times, and chains break and then turn into missiles.

For what it's worth,

Chris.
