No. It's a space that's difficult for me to access.
Brutal honesty: I'm too heavy to use the ladder and walk around on rafters safely. There's also not enough headspace for me to stand even if there were a finished floor up there.
I can get up the attic ladder a few steps. Enough to get my head, shoulders, and chest into the attic. I can shine a flashlight around and try to see something.
Brutal honesty: I really didn't want to have to fight off a scared, grown possum or something. While on a ladder that can't really support my weight, with bad balance and all. Years ago, sure.
