Also, you should really have more than one memory card. I have a card wallet tethered to my bag. So even if I were to leave a card on my desk, I'd have plenty more to use once I got on site.
I know. I will get another card. I usually keep this one in my camera at all times but Monday I took it out and forgot to put it in. I have never forgotten it since I had my second point and shoot and then I wasn't shooting a session so it wasn't a big deal.
