Great news you are thinking to relocate here in the future. I'm sure you'll love it here, much as we do. Even with the Little Bear fire last year, Ruidoso is still a special place as you've undoubtedly discovered.
Internet service really does depend upon where you are located. If you are truly in Ruidoso, Baja does an excellent job, and you have also DSL options with Qwest as well. If you are in Alto, where we are, Windstream is about the only game in town-which is not very good frankly speaking. I only know one person with Hughes service, and their comment is it's just a bit better than dialup, but not much. Mountain Alarm and Security on Cree Meadows Drive might be able to give you some ideas as well.
I guess I would really wonder if you need this, given the huge costs involved, especially if you need to run new services. This is not a high crime area, and if you have bare land, really you probably just need to check for squatters every 3-4 months or so. Again, just a thought, but people are extremely friendly and open here, and it might be more cost effective to hire a neighbor to stop by periodically and check things out for you. Good luck in whatever you decide, and hope you enjoy your new property!
