I have been looking around and I can not find any showcases occurring during the fall or winter except for the Perfect Game Northeast Fall Showcase on the 31st of August, and the Northeastern winter hitting camp(looks like more of a showcase). I am interested in showcases/camps around the Northeast area and also the Maryland, Virgina, Washington DC area but all my searches are coming up empty so does anyone know some showcase events which are occurring in the time frame of the fall and winter. Any help is appreciated.
