Sheridan Road runs the length of Zion with the lake just past the tree line, and in July the pavement holds its heat long after the sun has dropped over the prairie side of town. Adolfo's Sealcoating and Landscaping keeps the green and the gray both in order — mowing, trimming, planting and cleanups through the warm months, then plowing, shoveling and salt once the driveways go white. A drive cleared curb to curb, with the apron squared off and the walk to the front door opened, is its own kind of finished work. Summer or winter the idea holds: give the ground a clean surface and a straight edge. In Zion you get asked for both, usually inside the same six months.
