The Moog factory is definitely worth a tour, as is the entire Asheville River Arts District. There is an awesome scene going on there with lots of interesting old factories being bought up by everyone from craft breweries to tech companies to amateur welders. This is a bit off topic, but I could see a trend of tech companies moving to "rusty" cities like Asheville that are becoming cultural centers due to cheap real estate and an emphasis on the arts. VC will always be an issue, but Asheville does have the Tech Triangle (lots of engineering and science research going on there) close by, which makes that less of an issue. (Note: I am not from Asheville, but I love the area and go there a couple times a year)
