Tell me about it! Around here, you gotta watch out for all of the city-dwellers who come up to ski. They're driving their big SUV's, usually riding on 'all-season' tires, and acting like they're invincible. Sorry people, but 4WD only helps you GO, it doesn't help you STOP!
Several years ago, I was riding with my dad in his Toyota Echo in a heavy snow storm. He was driving a reasonable speed for the weather, but there was this Jeep Cherokee that decided to pass us. I saw it pull up along side of us out of the corner of my eye, and then all of a sudden it was gone. I looked back, and sure enough they were in the ditch. We went back and gave them a ride to the repair and tow shop around the corner. They were so embarrassed :D. Turned out, they didn't even have it in 4wd.
