Memory Card Malfunction

After last night's scrambled efforts to get shots quickly I dropped one of my memory cards at the beach. With a chilled out day we decided to go back and have a wander around the beach anyway in the slight hope that we might find it. I retraced my steps from the following evening using the pictures on the other card in the camera as a guide. All hope was lost after about 15 minutes of searching and I had given up...but as I looked down and kicked my feet I saw the little fellow sitting about 5cm above the high tide mark! Unbeleivable!
