Temps were in the 20's this morning. I woke up and checked the firebox of my All Nighter Moe, which I found still had some coals from last nights overnight burn. I tossed in a few pieces of pine to get it started up again, shortly followed by a link or two of cherry which coal up real nice, and topped off with some ash splits to last a few hours. I vary my wood types by time of day, outside/inside temps, and length of burn. What is in your stove right now?
