Wizofoz:
I don't know what you've done up until now, but the satisfaction of flying,mastering, and competing in something like a Pitts S1 is near the pinnacle of aviation experiences.
I recon doing 1000k in a open class glider on nothing but a couple of puffs of hot air pretty close (says me working on my B certificate
)
Sunfish: head out to Bacchus Marsh - three gliding clubs that operate just about every weekend, and start your real flying! If you want to stick with the cast iron thermals, there is a powered school there as well, that seems fairly quiet on the weekends!
