So here's whats up. Cronk MMA is gone, Cronks jits wasn't that great anyway. If you want to learn good BJJ and other ground/grappling **** check out the newly formed Sioux City Brazilian Jiu-jitsu club. Jesse Perrin is running it, he's about to get his purple belt from Romolo Barros, so he knows what he's doing. His Facebook is http://www.facebook.com/people/Jesse...00000521931973. He mostly does BJJ, but any serious MMA fighter in the area knows who he is, so he can help you find an MMA gym. I just train with him right now, but I would love to find a kickboxing or Mui-thai place. If anyone knows of any let me know.
