Don’t forget that southern Colorado is just cross the border of Northern New Mexico. San Juan, Colorado claims to be the oldest town in Colorado and is really an extension of NM. The point being, its interesting to note that "Mexican" food in Colorado may be from "Mexico" of 1800, not 2000, since this area was Mexico 200 years ago. Colorado "Mexican" food may not be from what we usually call Mexico, but rather recipes from original Spanish families who still live in the area. There is a small difference in cuisines (like use of many chiles, posole, fresh rather than refried beans, use of corns and squash, sopapillas, etc.) Some of this may also extend to the Denver area. Just a note, but I always find this intriguing to remember.
