I live in Class B airspace, but trained in it only to the extent that I've been told to avoid it and only used Boston App/Dep control for flight following. One day it would be neat to fly over the city. I see single engine aircraft fly over my house all the time in the summer so I know people are doing it. What's the procedure for doing this aside from getting the clearance to enter class B? I would imagine you'd get a squawk code and then get vectored. But what would the call up phraseology be and what could I expect to get in response as far as a route? Would I have to be very specific about my flight path?
