Today we hiked mile 406.69 to mile 424.91 with elevation gain approximately 3K and decrease of approximately 4K. We woke at 5am to find that it froze overnight and there was frost on the fly of our tent. Started hiking at 6:15 am. The day was cool and the weather appeared to be changing. We hiked with Guy all day. He was having shin pain and was worried . Jerry’s knee was also quite stiff at lunchtime as he had forgotten to take any Advil. We filled 12 liters of water at the Mill Creek Fire Station in prep for a dry camp. We have been in close proximity to highways for the past two days and the constant roar of loud motorcycles and souped up cars has disrupted any notion of tranquility. Loud cars seem to be an obsession in Southern California. I forgot to mention yesterday that a large rattlesnake was coiled and ready to strike a couple of feet off the trail. Jerry was oblivious to the danger. I said “move”in a forceful manner and what does he do? He stops putting me in the direct line of fire. I push him forward to get out of the snakes way. What is it that when you urgently want someone to move they stop as if they must validate your request!!!
