The longest human tunnel traveled through by a dog skateboarder is 30 people and was achieved by Otto the Skateboarding Bulldog in Lima, Peru.
He starts at the top of the hill and navigates the 30 people long Human Tunnel with the skill only a truly amazing skateboarding dog can muster. After achieving his life-long goal he gets a hug from his person and is surrounded my a cheering and adoring crowd. He displays all the emotions you would expect from a bulldog. That is to say, he was somewhere between taking a nap and apathy on the scale of emotions.
He is a true champion. Congrats Otto!
