You know, I have been thinkinbg about your post for a bit, and have come to the conclusion that you are onto something. GA IS boring when everything is going OK, and can be terrorfying when not. What do they say? Hours of boredom punctuated by minutes of terror?
When you compare GA to other interests like skiing, scuba diving, motorcycles, sports cars, it really does pale in comparison. It is a mode of transportation though but to really use it, you have to be very well equipped which costs even more $$$. It does get old on long trips, hour after hour, with your approach frequencies in your lap, and every so often telling ATC, Grumman XXX level at X....... That is why I prefer shorter trips to fun places as the flying stays fun, and you get to be somewhere you normally don't go. But I agree, it can get old, and the excitement/$ is low, and that is a good thing because excitement in GA usually means something has gone terribly wrong.
You are also correct about the social opportunities. If your objective is to meet a bunch of old, married, white guys, GA is the place for you!
