I recently moved away from the Sierra Vista area (to Ajo, AZ). I would recommend trying to stay close to Sierra Vista, or even Huachuca City (even though it is kinda dumpy). The closer you live to the border, the more illegal traffic that you will have going through your yard. I have a friend who lived out on Ramsey Canyon Road and the realtor failed to inform them that the rear door had been kicked in a month before she bought it. I lived in Coronado National Monument, less then 2 miles from the line and never had any problems, but I was only there for a year. If you go into the National Forest, there is an unlimited number of possible jeep routes. I would recommend just keeping your head on a swivel and be as far north as possible after dark.
