Rustyrivet I hear what you are saying. So many years and still not flying. Finding a dedicated instructor is not as easy as it sounds. I am just getting back to RC. I started visitng clubs in area and all are 1 hour or more away. First club I visited, designated instructor had not been around for a while. Pilots there would help me along. Second club had a Fly In so I visted. I met the club Vice President, an instructor, who offered to help me along. Well he let me down, didn't return my calls. I decided to go it alone.
So, I have 65 acres and I am doing just what you want to do. I have my runway dead center behind the house with open pastures. I've already crashed my first attempt. I found I could fly the plane but let it stall in a turn. Rebuilding for my second try. I'll keep at it til I get it right.
Now buying acreage will not be an easy process and could be a long term process. There lots of things to consider. I know cause I did it making the move from Florida to Texas. House and land was vacant for one year before I could move in. Big city to country transition was easy for me. But not for everybody.
You have an offer on learning to fly. I would take that offer and get on with your flying. Don't let embarrassment get in the way. Follow that dream. Then take your time, do your research and looking for that dream land.
