That would be awesome! The only hop harvest I've attended has been in my backyard, but I certainly don't have a need for huge farm equipment or even helpers, for that matter.
A brewery in western Virginia held a similar event a few days ago:

It was during the week, so work interfered, but I would have loved to go. Looking forward to your pictures!
