I dont have much experience driving in snow condition. Are highways mostly fine for driving in the condition you guys described? I drive a prelude... So I am worrying about my trip to new mexico...
When are you going? And where in NM are you going?
You'd be surprised. Most of the time the roads are clear and it is sunny and nice, but man, you see some gnarly shit some days. There's obviously really no way you can know very far in advance what the road conditions will be like (like, far enough out to plan a trip around it), so you'll just have to jump in, but if you find yourself in some hairy shit definitely take it easy. In the mountains of Northern NM I've seen pretty rough days where there are cars in the ditch every few miles. In general, most people get a set of chains to put on if they need them, also a big bag of sand or kitty litter in case you get stuck and need some extra traction. A little shovel is sometimes helpful too.
Hope that helps and I hope you have a good trip!
