This is a fun local website I stumbled across that highlights history and vintage buildings and old restaurants in the Oklahoma City area. http://www.retrometrookc.org
The mission from their website states:
"Retro Metro OKC is dedicated to educating the community and its visitors about local history by collecting, preserving, displaying and interpreting materials reflecting the heritage of Oklahoma City."
Very Cool, check it out, they have some neat old photographs posted online.
