On Saturday, July 17, a memorial to the passengers on Piedmont flight 67 will be dedicated outside Hendersonville, NC. For those that don't know, flight 67 was involved in a midair collision on July 19, 1967.
Very nice memorial site. I started several years after that happened, but heard a lot of talk about it over the years. If I recall, it was a charter with a camping group onbard.
