Jesse,
I do not fish many PA waters, but I do live in NY. As for me, I've never been "out west", and probably never will. I'd like to fish, there, someday, but chances are I won't. There are a number of different reasons. First, I don't have the money to travel out west, spending money on gas or flying, lodging and license fees. My family is HERE, so moving there is out of the question. I guess if I were single and young, I might consider it.
Most of us MUST make do with what we have, not that I'm saying it's better "out there". We put our efforts in to making what we have, better. I believe there are many great spots to fish in the east, it's a matter of locating them, improving them, and protecting them. Perhaps your friend just got tired of looking and has no taste for making things better. The grass ALWAYS looks greener on the other side of the fence, and it is often easier to just move away and not try to improve conditions where you are if that's what's needed. It's somewhat true that the west has a certain amount of attraction, however the east offers water which is deep seated in fly fishing history.
We need to cherish it all, protect it all, and continuously improve it all IF we are to continue fishing. One MUST learn to appreciate what they have.
I have a good friend who lives in west Yellowstone, on the Madison. He continuously begs me to come there, but for some of the reasons mentioned, above, I've not been able to go. He wants me to come to visit to exchange ideas, tie flies, create art, and fish, but fishing is the least concern. It's an extra added attraction. I guess it hinges on the fact that I've learned that fly fishing is not always about catching fish. It's the participation, the sharing and the experience that make it so great. Enjoy your time on the water no matter where you are. To somewhat paraphrase Alfred Miller (Sparse Grey Hackle), " The trout do not rise in Woodlawn Cemetery--Fish when you can."
