A few years ago I did a similar thing only it was flat batteries. The batteries went flat after about 10 shots, in a room full of new years eve party guests. I had a battery grip on the body, but I didn’t bring the AA cradle. I went all the way home charged my batteries and packed the AA cradle. When I reentered the room everybody cheered/jeered.

Being a nerd, I have now created a trip check list (on my phone) so that I don’t forget anything.

PS: I wonder how long it will be before the brain cells go totally and I forget the phone checklist… or even the phone.
