An amusing idea.
if there is a fifth season, possibly a have a scene on the bus to Camp Kikiwaka come to cross roads with signs pointing to other fictional towns in Maine.
Maybe signs pointing to Castle Rock and Derry in Stephen King stories.
Maybe a sign pointing to Collinsport from Dark Shadows.
maybe a sign pointing to Cabot Cove, "Murder Capital of the World" from Murder, She Wrote.
And possibly pass a sign saying "Welcome to Moose Rump. You should have got off at Cabot Cove".
