The last thing most Katrina evacuees probably want to see is water (tell that to the smart folks who're putting them on cruise ships), so we're guessing that Houston's newest guests won't be lining up for this weekend's canoe tour down Buffalo Bayou. But for locals, the paddle tour, which is part of the Best of Buffalo Bayou series, might be of interest. This Saturday's "Introduction to Ecology and Earth Science" will address the ecology and geology of the bayou and -- something particularly timely -- the history of attempts at flood control and erosion maintenance in the area. So essentially, residents who live near the waterway can find out what's being done to keep it out of their living rooms in case a hurricane hits Houston. The tours are led by Don A. Greene, a bayou guru who has been working to preserve Buffalo Bayou for more than 30 years. Paddle with Greene down the waters, and you'll gain some insight into what he calls liquid energy -- and even more compassion for our friends from Louisiana and beyond. Reservations deadline is 10 a.m. Friday, September 16. Tour runs from 1 p.m. to 5 p.m. Saturday, September 17. Participants meet at 5000 Memorial Drive. For information and registration, call...
