I agree and loosing interest also. I can't even say he is living out there. There has been a lot of nights spent with trail magic. I never hiked in the snow since I waterfowl hunt in the winters, but the mileage is extremely slow. How bad can his hip be?
I will be surprised if he completes NCT. I have zero hope for him to complete all four based on his performance thus far. His health seems fine, but the abundance of time being used and being stationary will cause the end to come. The sense of over projecting the goal to complete all four will take a toll mentally.
I was pondering that if many had confidence of his completion, where are all the major sponsors at? If I was a branded company, I would make every attempt to get my logo displayed and gear being used if I thought this "Trek" could be completed. Granted, I do not know his previous experience of backpacking/hiking, but from what I have read, I feel his mental state will lose emotional awareness and coping skills. But, then again, spring will be here and days will get warmer and longer.
