+1 to foxmoth's sentiments. I like driving and "having my own space," so unless the bus fare is ridiculously cheap, I take my own vehicle. I own a 7-seater for the space.
xrayalpha, I agree I need a bit more exposure regarding GA, thanks for the heads up on microlights though!
Genghis, I'm not sure what you mean about the PA28 being on rails. I did feel the turbulence though, but does not mean I had a problem with it --- in fact, I quite enjoyed the sensation!
