Over the years, I've managed to sort out most the other duplicate named (or located) casinos -- like the 2 Rendezvous, the downtown vs. strip Club Bingos, the 2 Silver Slippers, the Royals in LV vs. Henderson, etc.

The original MGM Grand (now Bally's) vs. current MGM Grand are easier, since I've been in both of them.

Todd, your article / maps on Honest John's are great! And Phil, thanks for your steel-trap memory!
