Dave, thank you for your very kind comment.
40 years ago that would be me. But the years have not been kind to me, too much collateral damage. Too many strained ligaments, too many pulled muscles, one too many instances of a shortage of oxygen. (That could explain a lot). Luckily never broke a bone.So it is photographing excitement only for the rest of my dicky mint.
John, I know you did not take this picture, as it is you who is pictured. It it useless to pretend that you have no taste for such activities---I know better! Please correct the misleading photographer's name. Thank you in advance. By the way, will you take your camera on your next flight?
