One of the most interesting sights we saw that day at the National Zoo were the orangutans. We saw this mama with her baby. And the baby sure wanted to climb.
But mama had the baby hold on about halfway up the tower.
But there was a tower and rope system that had two separate centers, they were designed to be able for them to transport on their own free will. Which was kind of scary considering that it'd be bad news if either the baby or the mama had slipped in their grip. What's below them is the pavement where visitors are standing.
The other orangutans were all sleeping though.
