Local playwright Tammy Ryan's still developing play, 'Lindsey's Oyster,' among the 8 productions staged at IUP during the Kennedy Center American College Theater Festival

Post Gazette: Festival, they call it.
Not the festival, and certainly not a festival, but just Festival, as in, "we do it this way at Festival." It's a noun, sometimes an adjective and maybe even a verb, subsuming everything -- a life-form of its own.
The fuller name is KCACTF, the Kennedy Center American College Theater Festival.
