My point is that you would not normally fly within 100' of an airspace

won't accidently bust into airspace?

I've done that many times. I just gave one reason you might want to do
that. Here's another:

Or another: Take a look at LDJ, hiding under a CBAS shelf south of EWR
(since we're writing about this area anyway). Note LDJ's TPA.

FWIW, a lot of pilots fear that airport for just that reason, though
given the opportunity most seem to get over it (my club keeps two
aircraft there {8^).

An interesting side note: the GPS-A approach into LDJ never enters CBAS.
Was that just a coincidence? By design to permit practice approaches w/o
bugging ATC? But it makes it very simple for those unfamiliar with the
area to get to the airport w/o being required to talk to a controller.
