Thanks Ron for the mental Image of the valley. As I sit here with the rain drumming against the window as it has been for the last 12 hours the wind bending the trees flat to the ground I can not help but wish for nicer weather, but maybe not that hot.
Still, looking forward to visiting Scottsdale again later in the year. Try to get their once a year at least and looking at the weather outside right now the sooner the better.
An Airbag style would be nicer to wear I agree similar to the difference between an old fashioned "foam block" style life jacket and a small inflatable tube one. Not sure they will ever be able to design it but who knows. Hope to see one of these in the next couple of weeks and try it on to feel how much it weighs etc on. Will post once I have tried it.
