I am sure that every local beekeeper from your area will be here tomorrow. http://beaver.extension.psu.edu/Agriculture/WPABEE_10.pdf
Even if you haven't signed up, you can at the door. You just won't be guaranteed lunch.
This is the list of vendors that will be there:
I also got this email response from Brushy Mountain's Rep.:
I will be attending the bee seminar this Saturday. We will have a complete booth set up for viewing. I will be taking orders at the show. All orders (except large truck orders) over $100 and are paid for at the show will receive free shipping. Most orders will come out of the PA warehouse.
I look forward to seeing you at the show!
