anybody know of any BJJ schools in Lincoln, NE?

i've been out of training and competing mma/bjj for a few years and want to get back into bjj... i live in lincoln, nebraska now and haven't a clue as to if there is a good school around here or not.... i know there are a couple in omaha, but i'm in dental school and can't afford the hour that it takes to drive there a couple times a week... hopefully my ug bro's can help me out!
