Yes, I went to Muir. I was the only one that showed up so I went by myself. I got there in 4hr 50min. Hot sunny the whole way. There were about about 40 people there, kicking back and basking in the sun. A group of ten showed up pulling a sled with a keg of beer. They wasted no time in tapping the keg and commencing to party. It was a festive atmosphere with music blasting. There was a constant flow of people coming and going. I reclined in the sun for about forty minutes and then headed back down. It was pretty slippery on the way down, but I didn't use snowshoes or crampons at any time. I'll probably do it again this Saturday. Same time, same place.
