A Juneau County deputy responded to a gas station near the Rocky Arbor Interstate exit early Friday morning for a fight on a Megabus.  The deputy said when he arrived a state trooper had a Chicago man, 28-year old Joseph Higgins, in custody for disorderly conduct.  Investigation revealed Higgins had pushed the man sitting in the seat next to him because of the tight seating.  The pushing allegedly escalated into a fight.  The deputy took custody of Higgins and transported him to the Juneau County Jail.
