Re: "There is even a 30ft wide flat dirty road that the planes would be landed on, but it would be a hard landing. "< 30 ft. of road isn't long enough for a 40 sized trainer while learning. Its pretty short even for experienced pilots. See if you can get some more help from a club. As redfox435cat mentioned, if I am at the start up area or flying my planes I am focusing on that and probably wouldn't even notice if someone drove up and was standing there. If I do notice, I will go over and see if they have any questions and see if they brought a plane with them. Usually if they do have a plane but haven't had the plane checked out before bringing it to the field, it will need some changes to be made before it is flight worthy. Ie. if the nose wheel is turning 2" in both directions it will need to be reduced big time!![8D]
