In my best Boomer voice I say, "really cold?" Really cold was my first winter after moving to Vermont when there were 30 days straddling January/February that never made it above zero, and bottomed out at 35 below zero.

Boomer anecdotes aside, and I'm sure non-transplant Vermonters or especially those from outside of Chittenden County have colder stories, I'll agree with others that you have to look at averages over time. We used to get below zero regularly, it only happens occasionally now. It's so memorable when it does because it is so seldom.
