As in any other situation, residing in El Paso successfully is directly related to what you and your family puts into it. Being from the midwest, I felt that I was in an alien world. There is NO green out there!
However, when I visited my daughter, I also visited the archeological museum, Alamogordo, and other places. There are National and State Parks in which to hike, hunt and fish. Carlsbad Caverns are within driving distance. I read up on the history of the area and even drove by the old Mission Churches which is through the barrios. They also have a more than acceptable Art Museum.
They have indian pueblos and festivals and Mexican music and concerts [Rock, Western, Country, and classical]. Try it, one of your kids and/or yourself might really like it.
They have rodeos and a minor league baseball team. The El Paso Community College and the U of Texas - El Paso are available.
I suggest that you and your family take full advantage of the area and check out the Ft. Bliss MWR site [for bargains], as well as, the State of Texas site for El Paso. Make a list of what to budget for and make [& take] the time in El Paso a learning experience for all of you. Use this as a "family project" as even 3 y/o can tell you what they want to see!
Best of luck!
