I've done very little research into Detroit but I do know that Lincoln Fitzgerald's Chesterfield Club was just outside of Detroit in Macomb county. The address "24845 Gratiot Av" is not in Macomb county. However, years ago someone said in one of my illegal seminars (probably 10 years ago) that either 24845 Gratiot or the 20715 Van Dyke (or both) were the addresses where drivers would pick you up and take you to the real casino. I assumed it was a mobile casino, but I have not done any follow-up and unfortunately do not rememebr who gave me the information.
