I was sitting on the back of my boat one summer day; snapping pictures of the kids doing stunts on the wakeboard. I had my $500 custom made prescription sun glasses perched on my head while my eye was up to the camera.
In a split second the wakeboard rope brushed my head and the glasses were "plunk" into the lake; I handed the camera to my daughter and dove in after them; everyone in the boat was WTF?, no luck. Gone. I'm still grieving that day
Cheers!!
