OK... who are you people? I was in cast B 1970 to 1972. I was also in a Sing Out. My sister traveled from 1966 to 1969. I've been FReeping for a while, but never thought I'd find any UWP alumni here.
I was a member of Sing Out Sacramento circa 1965 - 68 and turned down a slot on one of the National Casts (they were going to Russia) in favor of a full ride scholarship to Mackinac College (Where Up With People was founded).
