Is it Tuesday yet?

My Mondays off are quickly becoming less fun than my workdays, sadly enough. Today it was the nightmare of my own making -- I lost the only key to the cellar, which is the only access to our crawl space. The only access, of course, except through one of the foundation vents. So today I spent my day off wriggling on my belly through fiberglass, dirt and spiders to finally pop out in the little cellar.
Along the way, I peeked at the heating ducts (I kind of had to in order to crawl over them). I thought we had basically been pumping heat into the ground by not having the ducts sealed and insulated. Little did I know we were literally pumping heat in the ground. One of the ducts isn't really connected to anything, just blowing heat out, some of which accidentally makes it into the disconnected duct. That explains why 68 degrees just isn't so toasty.
I spent the rest of the day trying to get a new deadbolt to fit on the old cellar door lock I had to remove. And now I'm picking at the fiberglass left in my skin. Fun day.
