it could be light poles, but seeing as how the waterpark isn't open really during the dark, and already has night lighting, it seems odd. But very well could be, but perhaps a bit fancier than your usual light, cause these footers are made to support something of significant weight. I really have no idea, but it's interesting. they are all over the WWK park, with a fresh one poured today. Lights are definately logical, but why such a large footer? the footers are about the same if not the same as the ones supporting LL.
