There is decent free parking at the top of the hill west of the stadium. Look for the Triangle Fraternity house. Pull into the driveway. They'll try to charge you (even K-State brothers get charged). Just tell them you're going through to the public lot. There is a small public lot behind their parking lot. Don't park in theirs, tho. They'll likely have you towed. They can't charge you for the public lot. Its about 2 blocks to the stadium.
