2003, Resurfacing of the soccer field at Albion College
The soccer field underwent an expansion to give the Albion Soccer team a larger playing surface to utilize. Work included removing the existing sod, moving the scoreboard 50′ to the east, laser leveling the field, and then replacing the sod. When bulldozers were at work they discovered several watermelon sized rocks that were uncovered and then burried deep beneath the surface.
