Save time for eating. Astonishingly good food -- even an ordinary omelette becomes something special when drizzled with salsa roja and wrapped up in a fresh corn tortilla. The red salsa in NM is nothing like the salsa we get in California (which can be very good, but it is tomato based). The true NM red is just about pure chiles. And sometimes it is not very spicy at all, and sometimes it is. And if they ask if you want Christmas, they are offering you both red and green. Say yes!
Make sure to try some sopapilla, maybe with a little bit of honey.
Also, the new moon is on the 13th -- try to get away from city lights. The stars in NM are, well, out of this world.
