Messed up big time today. It was too cold to bike, so I drove. I got there, couldn't find many, then finally, I found a couple. Turned my camera on, and it said "no memory card" and at the top it said "Can't Record!" I was disappointed. So I proceeded to take pictures, assuming I had some internal memory. I got home, looked at my camera, and when I tried to view pictures (without the memory card still), it said "no memory card" and I realized I had token every picture for nothing. They didn't save.
