Todd-
I am a flight sim geek too. I think it's a great to way to keep your head in the game when you can't actually get out and fly. I used to love flying in Flight Simulator 2002 and 2004, but I don't have any Windows machines anymore, so I've changed to X-Plane, and have found it to be superior in a few ways. However, the selection of planes available isn't quite as good for the single engine taildraggers. They used to have an excellent Decathlon you could download, but they haven't updated it for the new version.
A while back I bought 2 USB joysticks for $11.00 and I plan to turn one set into rudder pedals, as I'm too cheap to spend $129 on the the CH Pros.
I do the same thing you do with a real sectional, follow the terrain to my destination using pilotage. In the older versions of FS, you had to download the better resolution land mesh files to get any accuracy, but Flight Sim X might be better by default. It was good practice for flying in Idaho this summer with jmtgt, but when he let me navigate us out of Big Creek, but I still got lost. It's tough following the terrain when you're at or below ridgetop level.
