As you know, I live in Tulsa.
I can't tell you the last time I had been to "Big Splash/Safari Joes". I have kids, I might have taken them once? They don't ask to go. We would however go down to Muskogee to their little waterpark several times a year. It just seemed cleaner, more up to date and it was made up with just a couple slides, family play area, an activity pool, and lazy river.
Sounds like they might make this a place that kids and parents want to go.
