I missed this TR the first time around. Thanks for posting. There are so few TRs from Coe... I think it gets overlooked even though it has the best backpacking in the bay area. It's funny, I feel like I've done the exact same trip- more than once I've set out at Coe to do a long mileage overnighter and found myself back at the car 20 miles later. I wish the area was more conducive to campfires... Like you pointed out, you stop hiking at dark and wonder what to do with yourself for the next 12 hours...
