YIKES, every year! We have some friends who remove the plastic periodically to let the soil "breathe" in the air, wind and rain. Flushing salts and restoring ecological balance and such. This may be a strategy for us in the future.

Our snow load is VERY minimal but who knows with climate change. If we get enough snow to raise concerns for the hight tunnel, I think there will be bigger issues! We had snow for two days last year.
