I was at the local dump. I try to look uninterested, but am always scoping out the metal dumping area. It is a no-no to recycle stuff that is heaved in the dump, go figure. I love to recycle. Read "get free stuff"
Anyway a guy pulls up and throws a computer chair that the back had broken off of. Well, not being one to go home empty handed, I procured the padded, adjustable, and rolling, seat half. It is the best shop seat that I have ever used.
