I need to go one of these years. I have a couple friends who have been going for years. They say it's well worth it. Both started going as homebrewers, and have continued going as commercial brewers.
I'll be there. From what I've heard from people in my club, it's really awesome. Not just lectures but actually walking the fields and processing plant. I think you actually walk away with a ton of product too. (not an actual 2,000lbs of hops but a lot)
