+1 10Â°f at night 15 - 20 days till spring Wouldn't that be nice. Heat regulation is easy then. We can dream. What I hate the most it the temps get in the 40s mid January, Thaw out the ground surface & melt the snow, muddy ruts & puddles, then freeze at -10. We'll be getting some heat from the sun in March, "breakup" starts. In April, the ground is Goushy (thawed top 2 ") Time to leave for vacation. Can do nothing outside.
