But with the GPS, I'm not sure how to
proceed. Should I just draw a straight line and file direct?

Yes. ATC doesn't care how you get there, provided you do it correctly,
as you file.

Even before GPS was ever heard of, I would file "direct" to Dulles and
DCA, ratehr than by airways, because I could do that using just VORs.
I was never asked how.

Until Jeppesen stopped publishing them, I felt their VOR/DME RNAV
charts were the most useful enroute charts in existence.
They had all the VORs but no airways at all, and they had the right mix
of detail at the most useful chart scale for my taste.
I used them for more than twenty years, and I still yearn for them.
