I was forwarded this link yesterday and thought it was interesting. There really isn't any description or measurements shown, but it appears that along this stairway one of the rises exceeds 3/8" variance allowance. I'm sure this exists in many parts of the country I just thought you all would appreciate it. Maybe it was even posted here previously and I missed it?
