From the Frost Valley summer camp blog (this entry composed, I think, by Hird Director Kam Kobiessi):
Last night, Sacky/Hemlock (13 year-old girls and boys, respectively) got together in the new theatre to participate in Al’s Challenge Night for their evening activity. Who is Al? Alformer Frost Valley camper, director, a camper and staff parent, trustee, as well as a summer volunteer. While here, one of his program offerings is Challenge Night, where cabins split into teams and are challenged to come up with the best celebrity impersonation, song, skit, counselor impression, counselor tug-o-war (on milk crates!) and other things. It was a rousing night, with counselors and campers alike cheering on their teams to victory.
