Summer may be both heating up and winding down at the same time, but there's still time to squeeze in a little fun at the OKC Zoo. If you've been to the Great Plains Museum in Lawton, you've had a taste of an exhibit like this, but the Zoo is doing it on a much larger scale.

The exhibit sticks around until November, which might be the better plan since you could mesh your own Dinosaur Expedition with the Halloween Haunt the Zoo fun too. Unique Things to Do in Oklahoma City There is no shortage of things to do in OKC.
