Best advice I can give, never trust any other vehicle on the road with you, always always watch the other guy. It only takes a second for the overconfident SUV driver to lose control and start doing ballet at 60MPH. I've seen it, scary stuff.
As for the whole ABS debate, I have a special, passionate dislike for ABS in the winter cause it scares the crap outta me as it feels worse trying to stop on a slippery road with my ABS than it does to lock the tires. This could be all in my head but on ice and whatnot (where the tires try to lock almost instantly) the system is cycling so fast there is hardly any braking being done. ABS is great on everything accept hard snow and ice. Just my little rant there.
Also, in a skid, you want to steer into the slide. Not sure if thats what the other guys was trying to say or not. Basicly, is the back of your car kicks out to the right, you want to steer to the right. The key to this skill is knowing how far to turn in, as it varies with how bad the slide is. Also remeber that when the tail comes back, momentum is going to try and take it out the other direction, in the case of my example, it will now try to kick left, be ready for it and compenate the same as before, steer into it. Some slides are unrecoverable, for those, pray for no traffic or trees and enjoy the ride ocne you realize you can't save it. I recomend large empty parking lots to learn this skill. With our cars, get going a bit and yank the e-brake to bring the back end out, release the e-brake and try and get it back udner control. You'll find it good practice, but also a whole lotta fun, lol.
I had to laugh at the don't drive a RWD in the wonter too. When looking for a winter beater I went looking for a RWD, or AWD. Now I have an 86 Fifth Avenue, lol. I can handle a RWD in the snow better than a front driver, plus backwards doughnuts just aren't as fun as regular ones! That's what I get I spose for growing up on rear drive with lots of dirt roads, snow and memories of Dukes of Hazzard.
