The first MVOR (Mississippi Valley Ozark Region meeting) was held in February, 1957 at Meramec State Park near Sullivan Missouri. Approximately a dozen people attended.
Middle Mississippi Valley Grotto is seeking a list of names of the attendees. A few are known, however there were attendees from Iowa whom no one seems able to recall.
If anyone has such a list, was an attendee, or knows of someone who was, please PM me.
