Around here there's a sliver of flat country where people live. Other than that we're talking forestry roads they're pretty good though, they don't build anything steeper than 25%. Hell ya you can get a long ways still in a 2 wd the roads are made out of blasted rock so traction is great albeit rougher than hell. Yup, you can go a long ways in 2 wd, as you tear up the rear tires beat the crap out of your rear end and drive line. Work the hell out of the suspension for the chatter and wheel hop. Or you can pop it in 4 low and idle up.

AFA school busses and delivery trucks getting around in 2 wheel drive in winter, same here. But they're driving on well maintained roads and the plows are going steady in a snow fall. But still it seems about 10 times a year these days the schools call snow days and close and half the rest of the economy follows suit.
