The tree tunnel at North Lake is in full color this weekend. My guess is that it will hold its color through Oct 5. This photo was made on September 26, 2012 with a Canon 5D MkIII camera using a Canon 24-105mm zoom set to 50mm. The exposure was 1/90 sec. at f/11 using ISO 800 with Polarizing filter.
