One thing I don't like about government low altitude enroute charts is
that they do not show the state that an airport is in. Try figuring out
which state an airport is in (and therefore where to look up an
approach) in the southwestern Pa area (Ohio? WVa? Md?).

BTW, I spoke with a charting guy at OSH in 2004 about this. He agreed
it is a shortcoming (Jepp has it) but nothing positive has happened.
