I've recently been to the Home for the Feeble Minded, and was wondering if you have a map of it, or if you know much about the tunnel systems, as I had some trouble getting around with them. Also, the abandoned concrete factory is very cool and I'm surprised many people don't recognize it. I wasn't that impressed with the interior, but the roof was amazing.
Just be careful at the concrete factory as it is now much more active. as for the map there is one around somewhere. ill see if i have a copy.
