If you haven't heard of it, you may be interested in WISPA [0] as it sounds like you're still doing some fixed wireless. There should be a PA state-level group/mailing list that you might be able to reach out to.
You should be able to find a list of other, similar ISPs in PA on their web site that you may be able to collaborate with.
Also, their bi-annual conference is in a few weeks in Memphis, TN. There will be "fiber workshops" that you may or may not find interesting.
That's my hometown. Im 10-30 min away from about any part. Might try to go if it's open to anyone. Trying to collect info to help new ISP's get started.
