I have excluded looking in areas where houses I am interested in have HOA's.
Not too many HOAs out here, at least not where I live. Maybe in Jackson or Cheyenne. Don't know. Where I live there are no building codes at all. If you build it and it falls down, that's your problem. No legal obligation for a seller to disclose defects in a house you buy either, so you need to have one inspected before you close the deal. If you build, you must have a state permit for the septic and if you drill a well. I'd suggest buying something with proven water... Lots of dry wells drilled out here.
Oh, and if you want to grow things, make sure you find a place with some actual soil. And fence. You are legally required to fence OUT any stray livestock or deer. They have the run of the place.

As far as "TV" is concerned
No idea. Have not had a TV in nearly 15 years. Lots and lots of satellite dishes all over the place, however. I'm sure you can look it up on line. Just put "satellite TV" in a search engine and pick a company with service in Wyoming.
what internet access is like out there
This varies widely, though DSL is pretty much available in most areas. I pay $30. a month each for DSL and basic telephone service. With tax and the other nonsense it comes to about $72. a month. Terrible, but I was paying $65. for combined phone and dialup. I've been told that dialup won't even be available much longer. Here in Newcastle, we also have a good wireless company that doesn't cost any more than phone DSL, but is just slightly less reliable.
