So apparently Sac City has the 2nd largest popcorn ball in the world. Which I would have taken a picture of BUT IT WAS CLOSED!!!! We will be back for you popcorn ball, as god as my witness!
Honestly there wasn't much going on in Calhoun county seat Rockwell City when we visited. It does contain a Carnegie Library which is kind of cool. Andrew Carnegie would build these for any town that provided the land and people to staff them. I'm not sure if it's still operational.
