Antigo, Wisconsin used IMPERMEABLE Covers with Insulation.

These photos were taken in the Spring of 2010 in Antigo, Wisconsin. You are seeing the turf as it appeared immediately following its uncovering. GreenJacket^® IMPERMEABLE covers with FOAM Insulation protect 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.
