Thanks for all the info. I know how difficult it can be to compile information for a book or for an internet list, and the need for collectors to contribute verifiable information to the Quest. Some day East Cape Girardeau will be a reference of the forgotten past, and it will be because we've had this opportunity here to clarify the real location as well as the $5/$10 chip discrepancy.
I think books about the Kefauver committee in Congress will prove helpful to others who seek information about illegal clubs that closed in the 1950s.
