Aargh!

I had a lovely day in Edinburgh today when I had a wander through Princes St Gardens, met a friend and we did various things, including going up Arthur's Seat which I had never done before.
It was bright and clear (though breezy) and I should have had some good pics - they looked good on the camera screen - but nothing was recorded. As I was going on the train and wasn't sure what I would be doing I only took the wee camera, the one with the memory card that had its pics deleted yesterday. (I took my blip with a different camera). What I hadn't realised (as I was seeing things on the screen) was that the card had been de-formatted and didn't record anything! 
It's re-formatted now (so easy, if only I'd known) so I've only memories, will have to return but the conditions might not be as good.
