<p>Mid-30’s is not cold if you are prepared (coat, hat , gloves, pants). -20 is too cold for anyone but that’s about one day in four years. That said one of the best parties I went to was on a night of -27 or so plus wind chill down to about -60. I ran the block from my car to the party. When I got back to the car the tires were so hard and flat spotted that it clunked down the street until they warmed up.</p>
