I've had plenty of shoulder season fires already. It seems like for a few weeks I've had a fire almost every night. I've been doing a half load or less and having a low cat burn that lasts into morning and long enough until daytime temps warm up. Sunday night, I finally got to have my first "real" fire of the season. We were away all weekend and when I got home it was 40 outside and 52 inside. Got a bit of coals going then loaded up about 70% full. Set the air to a medium fire and watched hell itself inside the stove for a couple hours before going to bed. Man I missed those fires! Lows in the 30s and I woke up to a house at 68. Highs were supposed to be in the 40s so I loaded 60% full and set a low cat fire to last throughout the day. 24/7 is almost upon me. I am both happy and sad.
