Oh, I know exactly how you feel, I was overjoyed when Chloe had her first swim a couple of weeks ago..and like you, I didn't have my camera with me. I've made up for it since though, I MAKE her go in the water as often as possible, not only to take pics of her, but I reckon it wears her out even more than her normal charging around does
Remember your camera next time...we need to see pics
