If you're into stuff like lost history, it's a really cool site. Also if you grew up in Memphis in the 80's and 90's it will bring back memories of arcades and skating rinks and chick fil a. At least for me. I've known about the site forever and they even link me in the sidebar, but I haven't mentioned it in a while and it's fun to revisit.
