Ari Goldberger found that plows had dumped snow on his bike path in Boston, so he and his friends decided to plow through the snow that was dumped. They built a 40-foot tunnel for bikes so they could continue their commute by bike.
The tunnel didn't last long, as someone put a bolder in the middle and knocked it down, but at least it made a statement for alternative transportation and having fun playing in the snow!
