That's crazy! I'm going to have to get out and about today to see the difference from where I'm at. Maybe if I was doing legit clearing/measuring the total would be different, but my little snowstake has been untouched and reflected a storm total of about 14" roundtrip. I'm probably no more than 8 miles max in a straight line from Portsmouth, Kittery and Dover and that seems like a huge difference.
To be fair, we've got some massive snowbanks here and the plowing took some effort. It's not impossible that my stake is too close to the house/patio and has some sort of blocking going on, but who knows...?
