Due to the Weather this is now a Discovery Kingdom Event!

let's go to Hurricane Harbor in Concord and enjoy the hot weather and water slides.There is also a wave pool and a lazy river.
Season pass holders can get non season pass holders entrance for $30!
Hurricane Harbor also has an amazing food package for $23 with tax:you get a meal a soda and a snack during your visit.
I think they also have inner tube rentals which might be somewhere between 10 and 15 dollars for the day.
