From US-34 take Gear Ave and travel North. Travel on Gear Ave (you will see Farm King, Target, Westland Mall, Shottenkirk, Deery Brothers) until you arrive at a "T" intersection. Turn west (left) on Mount Pleasant Street for .2 miles and immediately turn North (right) onto N Gear Ave. Cross the rail road tracks, travel past the trees and you will see the Administration Building. Big River Resources is on the second floor.
