New location, but still at Norwich, NY (Chenango County). https://cvara.net/our-events/bullthistle-hamfest/
Having not attended for the past two years, the only information I can offer is that when it was located at the grange hall, they had a reasonably sized crowd. I attended and bought a few things. The event was fairly new at that time. The next two years were affected by the covids, and this year's event is at a larger facility with better parking. As I often enjoy the smaller hamfests (this is not the size of Hamcation or "Dayton"), I am glad to see they have chosen a larger facility.
My wife and I were going to attend, but our plans for that were precluded by something else. A friend posted a brief video online and it looked pretty good. The facility looked amazing... newer, a bit more room, and more available parking. Another friend and his wife also attended and said that it was smaller than some hamfests, but still pretty good. If they use the same location next year, it could grow into an even larger event.
