Tracey, I'm glad you took pictures to post. I somehow erased (or lost) one whole session of between 50 to 75 pictures on my SD card. Not sure how I did it, but they're gone! It had to happen at the show, too, because session 1 is OK and a short 3rd session is all intact. My favorite was the second one you posted. That's the one he wanted to show me when we left the lecture in a bit of a rush.
