Cutting firewood. My neighbours (the ones who run the buckwheat mill) had a load of old sawn timber which they didn't need. They said that I can have them if I have any need for them. Earlier this winter we transported most of the timber to my place, and I sorted them into two piles. One for 'still good enough to be used as a construction material', and another for 'only good for burning'. Every now and then I've been cutting a little from that 'burnables' pile for firewood to heat up the sauna.
