Summer vacations a LOT of times lead you to water parks, streams, lakes, pools. So to capture that you'll need a water proof camera. I own a couple of them and use them to take pics at triathlons when they do the swimming parts. Buy a cheap one and you'll have to cross your fingers that the pictures turn out. Buy a good one..and you might be able to save your memorable time going down a monster water slide or swimming with dolphins...ALL that!!! This guy has one of the best testimonials for his water proof camera..watch this!!
