I push the snow back about 40'-50' in my yard down by the road. I usually do this first, then plow my driveway snow down to end of my drive, and into the yard.
You had better duct tape a reflector with 4 foot rod on that mailbox because the big stuff is coming. If you're on the wrong end of unfrozen Lake Erie this cold air mass might give you a lot of seat time. And if you take down the mailbox the mailman won't have any place to leave the Bills.... You have a nice setup there... Wish I had a front blade...
