It's the ultimate Boston transportation. On land…all those slow cars get in the way. There's public transit – the T — but if you're in good shape, it's usually faster to walk. Bicycles aren't bad. But on water, nothing stops you and there isn't anything important in Boston that isn't within two blocks of being wet. The harbor and the city are interlocked like wrestling squid, tentacles of water and land snaking off everywhere, slashed with bridges or canals.
