If you want bush flying in FS9 try flying around Nepal. Bunch of high altitude strips in the mountains, tough approaches, lots of fun when you have real weather turned on.
If I'm on VATSIM I tend to stick with the eastern US or western Europe. If I find the VUSCG is online I might fly a low alt smuggling profile into south Florida. I'll private text the ATC to give them a heads up but other than that I won't "talk" to them over comms. Occasionaly fly a Russian Bear bomber out of Cuba and track up the east coast ducking in and out of ATC control sectors without informing them I'm up there. It's surprising how many people will ditch a flight to scramble an F-16 or something to conduct and intercept and then escort me for awhile. Kinda fun.
