Whereabouts in Alabama? I recently spent a good deal of time there.
But, winter time work......
-Dirt work: Roads, landscaping, building pads.....
-Fencing: Winter is a great time for fence-building. Clearing the fence-line, digging post holes or driving posts.
These are the primary ones that I can think of.
But, hey, here we even have "winter" grass which needs some attention, so...
