On the topic of Tree Keys, I went up it yesterday for the first time this season and passed a loose feeling block that was much larger than I'd like to drop on my partner's head. I chalked an "X" onto the block which sounded pretty hollow when I knocked, and there's a smaller rock right next to it up and right a little that had some serious wiggle to it. I know Humphrey's has a reputation but this seemed like a pretty prominent hand/foot hold along the route and, being one of the easier ones, I'd assume it's more popular. I was just top roping it and didn't pay attention to how many bolts up it was but I'd guess it was around 1/2 to 3/4 of the way up? Maybe when someone goes to fix the bolt they can take a look at that too and see if it's as sketchy as I thought it was.
