Strange to think of our bayou as a treasure, but that's exactly what it is. Perhaps it was an oversight all these years, but most cities the size of Houston have either paved or commercially developed comparable natural landmarks. Compared to the Thames in London, or the Seine in Paris, or even Brooklyn's Gowanus Canal, our dear, murky, often aromatic central waterway remains positively primal, and the recent attempts to dress it up haven't changed it's character overmuch. So come find out where the past laps up on the banks of the present at this guided walking tour. The tour is free with an RSVP.
