There are a few brew-pub places in the Woodlands located right by the waterway. I have gotten some interesting night-time photo stuff there. We could do dinner and then walk the loop around the riverwalk. It is about an hour or so at a leisurely pace. With the early light, that might be a good alternative. There is enough artificial light along the way to make taking pictures handheld with fast film not much of a problem with a 1.4 or 1.7 lens
