En-Route
Most instructors I've seen in the past 20 years are young, low time, only instructing to build time, not for a career. Oftentimes they don't have much more total time than the student when he does his check ride. The fellow who taught me years ago had thousands of hours, in Stearmans and T6s, (WW2) and was a true wizard. Sort of a John mohr type. I wish I could have flown that well but did learn quite a bit from him. I don't see how one counts on it today for a decent living. Most GA airports , unless owned by some form of government, are on the edge of disaster.
