Yeah that's why I prefer winter processing too. Hard ground/no mud and I also hate being hot when I'm working so the cold suits me. I won't do it after March. I like Nov/Dec best typically and the major snow isn't here yet usually and it's cold/hard out.I always try to get my racks all filled up in spring, which is always a challenge, given my access to the wood lot is across some pretty soft and soggy ground, when things thaw in spring. I try to pack in the several dozen tons of logs while things are frozen, as my only other chance is in the July heat and dry hard ground.
Cold winters with hard frozen ground makes everything easy, other than getting frozen logs un-stuck from each other and the ground. The goal is to be sure all wood racks are full before the summer heat, to maximize the number of summers spent CSS'd.
