TULSA, Oklahoma - Chase away those summertime blues with a visit to the Tulsa Zoo.

The zoo is starting Two For Tuesdays. Purchase one admission, and you can get one for free.

The offer is good through the end of August. 

To beat the heat, the Tulsa Zoo is opening as early as 7 a.m. until September 3.

There will also be water slides and plenty of cooling and misting areas throughout the zoo. That's part of the Bill Chill held every Friday, Saturday and Sunday.

Summer camps will also continue through August with topics like Monkeying Around, Oceans Alive and Winged Wonders.
