Looks like my reply last night didn't get posted, so take two -

Greetings from a northwestern Pennsylvanian stuck in New York.
Well, maybe "stuck" isn't the right word - it's western New York. I'm almost in our Tri-State (PA-OH-NY).

Have you already checked out the Kilt Map? You can at least see the X Marks members near you.

I had a link for nationwide Scottish festivals and highland games, which had all of those in Pennsylvania, but it's broken.
