Fall on the Canal

When I look at the thumb for this view, it has a nice tunnel/arch shape, but that seems to go away in the larger view.  Anyway, the trees arching over the C&O canal and towpath do feel like a tunnel in many of the narrower sections such as this area.  This view shows off the fall colors as well as the folks out enjoying a warm fall morning.  I've posted an alternate view, taken a couple of days earlier in M&N, here, should you want to compare views.  (5D3, 70-200 f2.8 @ 170mm, 1/30s, f/8, iso 200, tripod)
