I've been flying in the northeast for years, and almost never get
direct. At least not in the Boston/NY/DC corridor. I suppose if I plan
to go via Albany, Cleveland, and Altoona, I can get what I planned on.

Agreed. Into or out of Philadelphia, NY City, and Boston airports, there
is no such thing as a piston aircraft flying IFR direct, at least after
6:00am to 11:00p local. I suspect that the overnight hours might be more
lax.
