In case you don't know, Buster and his family spent many summers in Muskegon, MI. It became an off-season retreat for actors by 1903. Buster's father, Joe, helped establish the seasonal community. Here is an interesting link about The Actors' Colony. They also have some good info and pictures on Buster and his family here.
