I live in Central Texas as well and choose Colorado because flying is much cheaper to Denver. I've checked into NM as well and it seems like the trips are generally within $100 of each other. I've never been to NM, but for basically the same price, I'll choose CO everytime. As far as driving time, it's only about 3 hours difference between Summit County, CO and Taos, NM. Why drive anyways? Flight $180-$220 depending on how far in advance you buy your ticket. I've flown to Denver for as little as $120 round trip from Austin last winter. Rental car $45/day. Think about the price of gas for your 2500 mile trip and wear and tear on your own car. The only way I'd ever drive is if I was going for more than a week. Not to mention the 17 hours it takes to drive. That's two days of driving. I'd rather be hitting the hill sooner.
