Dan Nienaber of Mankato, Minnesota's MankatoFreePress.com reports: A hard rock concert that drew one of the largest crowds ever to the Alltel Center in February also brought some problems.Several people had to be treated by ambulance staff or taken to the hospital, police responded to more than two dozen incidents in or around the Alltel Center during the concert and Alltel security staff dealt with something they weren't used to: a mosh pit full of bouncing, bumping and bashing fans. It's all expected to happen again soon, so a group has been formed to make sure everyone is prepared. "I think we're just trying to go in with our eyes wide open," said Eric Jones, Alltel Center marketing manager. "We kind of had a debriefing meeting after the Feb. 13 show, what went well and what we could improve on. We want to stay on top of it, that's really all it is. Ultimately, we want to protect the crowd from themselves." The group, which also includes representatives from Gold Cross Ambulance and Deputy Director of Police Services Matt Westermayer, has a few weeks to plan before SLIPKNOT comes to Mankato May 13. SLIPKNOT is expected to draw the same type of raucous fans the BUCKCHERRY and PAPA ROACH concert did on Feb. 13. Read the entire article from MankatoFreePress.com.
