I didn't read all of this because I am in denial of the arrival of winter.
But... my opinion (you know the saying) is I might like to try something like this once - BUT not tell anyone about it unless they see me and ask WTF? Exhilarating challenges help a guy feel a sense of primitive victory and make some of us feel more alive. HOWEVER I would not do it for press exposure or the admiration of bloggers; or if I was the support system for small children, etc.
Kinda what Adrian said
Because I did not read the thread fully I have no idea who I opposed or supported nor is it important, just another post in a stream of flyfishing consciousness (or semi-consciousness in my case)
