Here's some shots from the lower and middle part of Bidwell Park in Chico during the fall. Most of these were taken from the road going through the middle of the park. I'm sure there's both better scenes and more fall colors off the beaten path.
All of these shots were either with a 24-105/4IS or the new 70-200/4IS. I absolutely LOVE the 70-200. Of all the lenses I have and have used, it's simply the best.
