Does not really fit my interpretation of "weathered". "Weather", yes. Due to the wording of the challenge description however, I have to consider any weather related images as appropriate.
I like this photo. It is nice and sharp with a crisp focus with good tones and the lighting is niether too dark or too bright. If there is anything I can comment on it would be a personal preference with the sepia tone. I just don't think the sepia screams summer time because to me it gives the image a slightly cooler feel.
i like that you used a fast shutter speed to capture the water in the air (rather than the soft-water affect). i like the way you also used the category title for more of a current event. we have a water park like this near my house and my children love it! this is an excellent shot. i'm not a member so i can't vote, but if i could - i've give you a 10! and, she's a beautiful little girl!
