The Forty Grand was run by Llyod Hickey. He ran at least 4 different establishments that had cards. Forty Grand
Lloyd/Sunny
Lone Oak Bar

"Sunny" was Mrs. Sonja Cantrell. She was in operations with 2 known Clubs with him. (Lone Oak Bar was the other)

I have seen a reference of him running 2 other Clubs. 49er and Rex.(without much evidence)
