I see you slipped some New York teams onto the list. Was that just a mistake, considering other notable New York teams within the Metro East region were omitted?
Yeah, kind of a mistake and kind of they play a lot of the NE teams throughout the year. We included CT teams because, technically, CT is part of New England, just not according to USAU, but some teams did manage to sneak in there.
