Carbon Monoxide!?
Weird. The smoke alarm went off, not incredibly odd when I am using the fireplace, but it wasn't the smoke detector. It was the CO alarm. I was totally surprised. It had never gone off as long as I have had one, over many many years. Yep, after resetting it a few times. It was getting a reading over 200 ppm CO. When I took it downstairs I got a reading near 300 ppm. I started getting light headed at this point. After thinking maybe the furnace heat exchanger failed and puzzling around a bit I figured out what happened. As part of the huge winter storm that recently covered almost half of the US, we lost our electricity. So, being well prepared, I rolled out the generator and started doing what I normally do. The generator (although it was completely outside) was creating CO to get in the house. Using the fireplace draft (and possibly other leaks) the whole house created a vacuum around the seal of the basement garage door. After the CO got into the house the forced air heat...

Night hikes are great. Experienced my first one just 2 weeks after you did, except it wasn't a classical 'hike': it was part of a 128km alpine ultra-marathon in Northern Greece. It took me almost 29 hours to finish, so it included the whole night on the mountain. Awesome experience, I have to say, to be all night in the forest, not seeing much, being focused on your run and the noises in the forest. Will do it again this year :)
