Thanks, everyone, for straightening me out. I am still on the alert for that one, tiny but significant, show stopper that will torpedo this whole crazy idea and I thought this was approaching that. My refusal to fly, which obligates me to plan for 6 days of round-trip driving, is reducing my on-trial time as it is so it is good to know I don't have an additional expense of acclimatization time. What the hell do I know? I was leaning towards not camping high but from a perspective of not ending a day with a climb and to avoid making camp in the dark if getting slowed down by the terrain.
If it isn't obvious by now, I do overthink things but, rather than discourage it, have developed a habit of limiting it to up-front planning and recovering from derailments.
As an update to a previous thread called "sanity check", I am still on, and on hot, with the next decision point being after the 10 day AT hike thru SNP in late April. Camp-craft and being able to carry 10 days of food are the goals for that backpacking hike with my daughter. To address Sredfield's comment about eating enough, I have adapted to a lo-carb hi-fat diet that is dense in calories and also is pack-volume efficient. "Hitting the wall" was an unfortunate, but inevitable, part of that process to get the body to convert to fats & ketones as the go-to energy source. I have been doing that since 2014 and have gone through a number of physical and working schedule extremes and nothing has indicated a need to rely on carbs for fuel.
When stuff happens, happen back!
