This has been the subject of lunchroom chatter in Tulsa for the past couple of years, but outsiders are just finding out. In 1957, a Plymouth Belvedere was buried along with a "time capsule" having items of that era in it. The idea was to dig it up in 50 years, at the Oklahoma centennial celebration.The time has come. It will be unearthed on June 15, 2007.
