Left at 1:00 am under a full moon. Reached the summit at 9:30 and hung out for a while. Took forever to get back to the car but we were drinking a beer in the parking lot by 6:00 that evening. A perfect day - the sore feet were well worth it.
Got an alpine start at 3am. Doing the switchbacks in the dark was nice. Hardly felt like we were climbing. It gives a whole different perspective when you can't see the progress you are or aren't making.
