Sooooo...we'll be discussing this over breakfast then?......
We can't get too organized due to the fact that the state wants all sanctioned "organized" trail rides/events to be insured.
IIRC, that's how it became a loose gathering of known associates who just happen to show up at the same time every year & accidentally pick the same trails to run.
Maybe someone who knows more about the finer points of that generality would care to throw in a couple cents worth?
