oh yeah those did look cool, we actually stopped there a couple of years ago before going home, so I saw those a little too late. It was August but the water was still running so it was still fun for my little girlies.Btw if you haven't been before/recently, there's a little mercantile type place a little bit before the Ranger station where you pay. They have these sweet sandboards you can rent for $20 for the whole day and they're sooooo much fun
