I live on a runway and I notice the decline in general aviation. Used to see and hear aircraft flying over all the time, now other than aircraft around the airport here, I rarely hear a GA airplane fly over.Yep. When you have a runway in your front yard you are too busy flying to notice the "decline of GA".
Same for boats on the nearby Ohio river, used to be on the weekends the river was full of boats, now even on a nice weekend you rarely seen anyone on the river. People are really hurting financially. Checking the activity at the local tower controlled airport taking away the commercial activity, maybe one or two GA takeoffs or landing a day and most of the time they are transit aircraft stopping for fuel.
