Getting the group of rambunctious youngsters to and from the forest would be a far more time-consuming chore if it weren't for a special fleet of wheelbarrows, all of which were paid for with donations.
"This is the most practical solution for transporting them. It's like a little school bus," said Key. "Without the wheelbarrows, our volunteer babysitters would have to carry each one. It's quite hard to take two, three or more young orangutans out to the forest, but this way we can pile them together, and they seem to really quite enjoy it."
