Forgetting something?

Have you ever forgotten something necessary for a shoot?

Do you keep a written list of things you need to bring, or do you do it by memory?

Today, I brought my camera to work, as I wanted to take photos of the nuclear machine (to use for patient literature). When I went to use it, it said "no card." Arghghgh. I can see the memory card now, sitting on my desk at home in my office.

I've had to buy extra flash batteries on the way to a wedding because we remembered them on the way.  That's the worst that's happened so far.
Oh we forgot a memory card for our backup camera (different brand from the main camera) at a fashion show, but we didn't need it.

At my last boudoir shoot I forgot I had taken a couple snapshots earlier of my daughter with her new Hannah Montana guitar and microphone singing on that memory card.  So after while uploading I had to seperate the boudoir shots from my daughters shots, talk about a mix of drastically different images.
