Rusty, I wouldn't be so sure that cattle on a ranch won't mind having an RC plane flying overhead. You may be right the cows won't care, but the rancher probably will. Our club is a comfortable distance away from a small ranch, but our planes occasionally cross the fence line on a long approach turn. The rancher has complained numerous times about the safety of his cows, and I can see his point. You also have to think of what you're going to do if your plane crashes over a pasture that you routinely fly over. Being a fellow Texan I'm sure you know how particular people are about their land and uninvited guests.
