It has been awhile since I've out with a pack, carrying at least 30 pounds (I don't weigh. Don't see the point.), and I could feel my body complaining for days afterward. Warren Lake, near Truckee is a beautiful trail, and like all beauties, it's difficult. About 14 miles roundtrip with a mad scramble towards the end. You could do it in a day hike, but then it would all be a rush both ways. Get in, get out. Move move move.
I do this to relax, you know. It clears the head, and I've needed that badly as of late. It always feels like I need it badly. I was listening to a podcast the other day that said you need to treat sleep like food, as an essential bodily need. I've disregarded that little gem for years and it catches up. I think it catches up in the way you think, in the places your mind wanders towards - dark places. Your body longs for sleep, and it will get it from you or make wakefulness unbearable.
All pictures were taken while it was sunny. In reality, temperatures ranged from hot to cold to hail. I don't show those parts. I would highly suggest just getting a GPS tracker and parking at the very beginning of the entrance. It's easy to lose your way, and technology can help.
