Good bouldering gym in Nebraska or Kansas City?

I'll be driving from Salt Lake to the Red River Gorge next week and am looking for a good bouldering gym to stop at and break up the drive. Preferably somewhere along I-80 in Nebraska but if there's nothing really there I'd be open to other suggestions between Eastern Wyoming and Kansas City.

When I was in Omaha for an adventure race last spring the guys from there were talking about a gym that was supposed to be opening in a big grain elevator right nest to I-80 close to downtown, but I don't know if they ever opened or not. Might be worth looking into.

The University of Iowa in Iowa City has a new Enterprise wall. Just off I-80. Supposed to be really nice.
