I really enjoy your posts and the logical development you employ. I would only add a very significant point.
By my calculations i rekon he would have worn out at least 6 pairs of sandals if not more based on a mate of mine that walked hundreds of kilometres in thongs and knew they were good for 500 k's. So I rekon leather should double that....... I need a scripture . Mate, I'm with you on this. It don't make sense.
You are the kind of bloke that sharing a beer with would transcend the piffle that is thrust upon those of us in the process of slip sliding away.
Thank you
