I just spent a few days in Exmouth visiting my Dad, he's a typical 'run for the sun' kind of retiree (I met lots of retiree's up there) and seeing this thread again makes me think 'I want to do that when I retire'. I don't want to mimick what you've done but to spend the hours making and thinking and re-making to create someting like you have would be an awesome feat
big kudos buddy
