Each time we build a new play structure on Young’s Hill, we connect it to nearby structures using fire hose. This allows the chimps to move from place to place without touching the ground, a feature that is particularly handy when that ground is covered in snow. We also shovel pathways for them, but hey, tightrope walking is way more fun.
Their balance is incredible, aided in part by those opposable big toes.
And when they lose their balance, they can always fall back on their superhuman strength.
