Obviously there are beautiful sunny winter days. Roads can be clear for a week, but my wood lot is not plowed out, and pallets are froze to the ground. Last year I was cutting/splitting almost ten days into January before the snow piled up and temperatures dropped. My forklift starts hard nearing +20, and hardly runs long enough to warm up to load a pallet or two. Winter customers usually want 1/3 cord at a time. If I'm processing wood then it runs longer moving logs and pallets. In the past I've moved things around, cutting/splitting into ten cord piles, and bundling in the spring. Turned out to be a lot of extra hand work to palletize from piles. Not difficult, just time consuming, when the weather was nice, and I could be palletizing straight off the splitter-conveyor. Don't know that I gained anything by doing that.
The flip side of not delivering is that customers run out and buy from someone else. I often hear what others are producing and selling in the area. They're buying habit probably will not change however, as they have limited space stacking in their garages.
The first winter I sold wood I delivered a cord and a half to two neighbors in a rural subdivision ten miles from the house. Drifts were higher than the cab of the Top Kick 5500. Although a sunny day the winds picked up, and running empty on the way home visibility was zero at times in the cut, and on the flats. One day I got stuck three times...in my driveway.
Empty it would get stuck on a flat spot. I carried chains from an old Buick that I would throw under the wheels, and later added several buckets of asses.
One woman I delivered to said don't deliver today as she was plowed out but got blown back in again. Either she was blown in or I was stuck at home. This flip flop went on for days, and it took a week to get to her place. Then we got behind a plow truck that socked in the end of her driveway. I sat in the road and a buddy walked up to see if there was a place to turn around up the drive. The plow truck did a 180 at the next road, came back, dropped the wing plow and opened up her drive apron that he had just piled up moments before. I soon learned she had recently opened a local pizza shop in town, as she gave us each a coupon for a free pizza.
As lone wolf noted, winter is a slow time for some of us, and a great opportunity for more sales, but I'm going to pass when the snow sets in.
