Get to planning and get your vacation days turned in, as September 15 & 16 will be the weekend for the 39th annual Quarry Cup (CRTC Rounds 5&6). It is coming up fast.
If you search for the Trials site, on google maps it will pinpoint the pavilion (where you check in).
FWIW, Trials site is about 12 miles north or so of St Joseph Missouri, on private property with locked gate.
Here is the flyer.
