Genuine question- do they like, do out with the intent of swimming with their clothes on or is it like a "we're out and about and we're hot let's cool off"?
I think some girls just decided to cool off, and others like to swim in the fountain. We've seen the same girls in the fountains on different days. There's another category of girls. These are the adventurous ones. Today they bathe in the fountain, tomorrow they will ride roller coasters, the day after tomorrow they will go to play paintball.
