We actually toured the NC brewery this past weekend.
If you're heading in the summer, I would check their website now to try to book a tour. They seriously book up months in advance. We couldn't get a reservation for one so we showed up at 11:30, put our name on the 'stand-by' list, and drank beer hoping for no-shows. You can actually walk through a lot of the facility un-guided as the brewery was laid out with visitors in mind.
We luckily got on the 12:30 tour and it kicked butt. You get a full tour of the facility (which is huge), including a trip to the hop cooler where you get to break hole-cones off large hop bricks and rub them in your hands to get an idea of how a brewer might select a batch. They take you to a tasting room where you get a flight of about 8-10 SN beers to cap it all off. Mind you, the whole tour is FREE. We had a blast.
As for Wicked Weed, the Funkatorium is a must...assuming you like sours....hell, even if you don't like sours go anyway. you will afterwards.
