CSMC trip. Car trouble on the way out delayed us 90 minutes from our casual start. Clouds threatened what was supposed to be a clear day. Biked a little past the turn off so got in a bonus hill climb. Hands on scrambling up to the gendarme that was good fun. Loose on the final 100m summit push. Rain started as we approached summit. Rain and wind on and off on the way down made for wet and slippery slabs and delicate downclimbing. Stepped on a chockstone at gendarme that collapsed adding a little too close for comfort drama. Nice ride out to parking lot with minutes to spare before headlamps would be required. Escorted Bert's vehicle home after 10 hr push.
