We made it from last Halloween, thru Christmas, Thanksgiving to St Patrick's day and then some, without needing to use a window scraper to clean the car windows. It was a very mild winter, with snow totals of less that 4" before New Years, then less than 20" by the end of Feb. But then we received almost 24" for one day in early March. Jane was excited because she had never seen snow piled so high.
