Thanks to Doug Dobbs for posting this on Facebook. I am not an organizer for this event, which will be hosted by Williamsport and the National Park Service and which will take place July 13-15 in Williamsport, Maryland. So I only know what you see here, but it looks like it might be interesting. If I can get a kitchen pass, I think I might be there:
