I will be travelling to southern Oregon in 2 weeks with a couple of free
days to make the drive back to Portland, and am curious what the
photographic opportunities might be.  I've visited the area in summer and
taken the usual spots on the seacoast, but never fall.

What will the fall foliage be like at that time?

Any unusual seasonal opportunities (like migrating wildlife)

Any reason to take an inland route instead?
