Spindle Rock is a YC on the West Branch of the Westport River, in Acoaxet, MA.  (The west branch was originally called the Acoaxet River).  There are a few Stur-dee Cats on the Westport River - they are manufactured right over the border in Tiverton, RI, so naturally one finds a flock of them nearby.  The beetles of Spindle Rock cordially welcome, and encourage, their interesting cousins to race at this event with them.
