My family and I took a little weekend vacation to Omaha, Nebraska. We decided to visit the zoo on Saturday afternoon.

The zoo in Omaha is one of the best in the country. You need more than a day to see it all.

Polar bears, penguins and even stingrays are just a few of the things you will find there. But probably the most interesting of all are 600 pound all muscle monsters that you can get face to face with thru protective glass.

All zoos have monkeys, but this place has gorillas. When these creatures walk, you see muscles flexing that make the weight lifters at your gym look like wimps.

You try to imagine the strength they have. We noticed big injury marks on their bodies and wondered what their fights must look like.

Well watch this. Here's gorillas brawling at none other than the Omaha Zoo:
