Bill I like you hangar at a non towered air park. When coming into the pattern or entering the pattern, I over fly the runway midsection. I then enter down wind. I also use a TAS. There has been a couple times on takeoff and climb out I had GA traffic cross the air park mid section at pattern height just passing through. They are trying to stay under class c airspace for class c airspace starts on the north side of our 27 -9 runway.
Enter the pattern midsection and use a TAS along with your eye's...

Smart flying is safe flying.
