Let's go to the TN Safari Park!

We went here and loved it! They have hundreds of animals in large, clean paddocks with a trail that you drive though. If you like, you can even buy food and feed the animals from your car window. Even better, if we have a group of 15 or more, we get to take their bus on a special route with a guide, although that would be an extra $100, which works out to an extra $5 or so, assuming we get 20 people going. Cost for the tickets if we get a group is $14 per adult and $12 for children. It is a two hour drive from Nashville, and I hope we can get some carpools going.
