A man named Benjamin David has found a way to circumvent all the fumes, noise, road rage and sheer tedium of rush hour traffic. Every day, he straps on his necessities in a water proof bag, and hops into Germany's Isar River in Munich. Then he does it again on the way back. The BBC reports that David swims a mile and half every day to and from work rather than deal with the roads.
Yes, his computer is in there.
David says he wears a wetsuit when it's cold, swim trunks in the heat, and he has no problems except for folks mocking him from the shore.
