I grew up in the 70s and 80s, back when math was math and there was no such thing as "new math." But it seemed to work because I even remember The Transitive Property of Equality... If A = B and B = C, then A = C.
So let me posit the following: Preppy = Lacrosse and Lacrosse = a sport Cascadian kids now play, then Preppy = Cascadian kids .
If lacrosse is like other preppy sports popularized in the Northeastern states, e.g., rowing, it will be adopted, played and improved upon by the Cascadian. (Side note: some of the best collegiate rowing teams in North America hail from the Pacific Northwest and the west coast of British Columbia. More to come on that later.)
Yet lacrosse is different from other preppy sports in that its origins can be traced to Native American and Canadian beginnings from over 1000 years ago. The sport was exported to Europe, where it picked up preppy style points, and then it was imported back to the US and Canada.
