You realize you aren't supposed to have above average snowfall winters all the time. Pretty sure 16-17 was AN there for snow. Are you 10 years old? Winters generally do NOT feature blizzards.
November on the weeklies sort of has a weak signal either way. My guess is on the AN side, but doesn't seem like a furnace. Maybe if anything more + departures to start and then slowly losing those anomalies.
1986. I think it’s just how it’s built. Gets some decent sun especially in summer. Windows are Anderson so they are fairly efficient.
I did bake a chicken so maybe residual oven heat helped haha.
