The museum is very nice but small. You can see everything in a couple of hours. It is worth going to see, IMHO, if you have an interest in the Johnsons (and especially since you're so close). We found Chanute to be a nice, small town with very friendly people.
"There are two main galleries, one presenting the Johnsons' story and another of African ethnographic exhibits. Additionally, a smaller temporary display space features traveling and changing exhibits.
The museum includes a shop offering Johnson books and video copies of their movies. The Museum Shop also carries a selection of ethnic items from Africa and other parts of the world.
The museum has garnered state and national awards and has been named the No. 1 Museum in Kansas."
Go see it! IMHO, it would make a nice weekend trip for you since you're so close to Chanute.
