My family could not afford summer camp for my siblings and me in the 1950s and 1960s, but I did attend a one week late summer "camp" sponsored by the North Carolina Association of Jewish Youth in Hendersonville, NC, across the lake from Camp Blue Star, the all summer Jewish camp.  For teens only, it was well done and a great chance to meet other Jewish kids, especially for those who, like me, were the only Jews in their schools.  I do not know how the adults became involved, but I am very grateful for the opportunity they gave us.
