It is that time of year in Austin where the evenings start getting cooler and it makes it nice to get out and walk.  This evening, I started at Ninth and Congress and headed for the loop around Town Lake.  There were a few art installations and groovy flowers along the way.  On my return to Congress Avenue, there was a flock of tourists anxiously awaiting the bats to begin flying out from under the bridge.  And of course, the sunset colors on the city were most beautiful.
