While I first measured 14" on my deck, but that was near the house. I got 16" on the far end of the deck, and I believe I got a total of 18" including the 2" that fell during the day.
I have never gotten stuck before in my driveway. Other parts of the yard, yes. Driveway, no.
I ended up shoveling four times so far as I work my way down...
The small green posts with the white tops sticking up (you can see them better if you click on the pic to get the full-size view) are I believe 4' tall, and the garden fence is 5'
After nearly three hours since I started shoveling my way out of the front door, I still got about 75' to finish.
If we have anymore snowfall this winter, I'll have to just keep going out every couple hours and pack the driveway backdown again.
