Interesting I am from Portland, Oregon but have family history I Tulsa. My dad was born in 1920 in October. Been back there a few time but never knew this happened, close to the part of Tulsa my family lived in. Didn't even heard about this till the 100 years anniversary. In many circle my dad was thought of being black. This was because of his darker skin color. Thanks for bringing this part of my mom and dad hometown.
