Years back, I was flying with my Dad and they wanted to get some pictures of
a relatives house. The problem was that their house is under the Class C of
Nashville (BNA) and directly under one of the approaches. It was a slower
time of the day for BNA, but by telling them what we were doing and how long
we would be doing it, ATC accomodated and we were able to make several
orbits of the house and take quite a few pics. Got REAL close and personal
with a landing MD80 in the process, but they saw us, we saw them and ATC was
involved the whole way.

Was my first experience in learning that ATC doesn't have to respond to
every request with the same phrase
