Do you only talk to towers? Possible. But tricky in some places.
Anyway, are you saying you almost always stay below Class Bravo?

Yes, the only time I talk with controllers is when I am entering the
airspace of a controlled field. When possible, I stay under or over class
B airspace. I have gone through Newark once and Orlando once, but
generally I avoid the Bs one way or another.

OK. Then, FYI, expect an altimeter setting whenever you contact approach,
departure, terminal or center. I guess I'm just used to almost always
talking to some facility when I'm travelling.
