This is another one of those places you pass by countless times before really noticing that it's there. Then, when you do, you see it each and every time.
On this particular Sunday afternoon, I finally decided to stop and take a look. The back corner is severely undercut with little support, and I suspect it won't be long until it gives way. The floors are becoming pretty dicey in places, particularly upstairs, but if you watch your feet and stay close to the walls, it isn't too bad.
All in all, kind of a fun place to check out. I'm glad I did.
