Rockford, IL used IMPERMEABLE covers and vented in early fall.

These photos were taken in the Spring of 2010 in Rockford, Illinois. You are seeing the turf as it appeared immediately following its uncovering. GreenJacket^® IMPERMEABLE covers & Insulation plus venting protected the greens from ice damage, crown hydration, desiccation, and help to keep the turf dormant during those freeze-thaw-freeze cycles, resulting in healthy green turf in the Spring.
