Tim, best of luck to you in whatever the future holds. Not sure what you are going thru, but I see we are about the same age, and I too, have been feeling like I need to make some changes. Flightsimming just doesn't seem to be as fun and engaging as it used to be and I have been feeling "out of whack" in several areas of my life lately.
While I'm not going so far as to remove FSX or any of the other sims I have, I think I will also end up stepping away for a while in the near future. Sometimes I wish I had a Harley and could just jump on the thing and start riding, nowhere in particular, just wherever the road leads....
Take care man!
Darrell
