I'm interested in taking some flying lessons. I probably won't go so far as to own my own little plane, but it would be cool to just know how to fly one of those small planes. Is anyone a pilot of any sort? What's it like? How long does it take? Is there enough standardization that you can quickly go from one model of plane to another, or do you need very specific and long training for each new type of plane you learn to fly? How much do lessons cost?
