I'm another 84h rider, and I got caught between Dinge and Tinteniac on the D20 at a tiny place called Trigory. Fortunately, it had some large oaks that I sheltered under. It hosed it down for 5 or 10 mins, which felt like a long time to be stopped, but pretty soon, it passed. I guess this was at 8.50pm. It was coming down very hard and most of us were hugging trees, although there were a few hardcore folks riding still.
