Somewhere, there is a museum for everything. There are two museums for kazoos - one for metal, one for plastic. Oklahoma City has a museum for skeletons, in addition to this. Seeing them back to back may have cost this one a star, because while I'm sure it has no equal amongst banjo musea, it just feels like a guitar museum with different shapes. I learned that in the 20s and 30s, banjos were so "in" that there were 4-figure and 5-figure models made, comparable to any top of the line guitar in the succeeding decades. There is a vast collection of gold plating, mother-of-pearl inlay, intricate woodwork, you name it. This year only, there is a Steve Martin exhibit with his banjos, which adds a star of its own in my book.
If you love banjos, or bluegrass, or the Roaring Twenties, or anything else remotely related to banjos, then definitely go here. If you just love unique museums, it's pretty cool, but if you're strapped for time, I'd recommend Osteology Museum first.
Note - limited street parking, meters. Assume 1 hour to get through it for the sake of meter feeding, though you will probably have seen enough banjos after about 40 minutes.
