Strange Shadows

I really like this image.  It is a panorama taken at Spring Mill State Park (about 9 images, total is about 200+ degrees) last summer.  While it looks like the shadows in the foreground are parallel, if you look closely you will see that the one in the center (from the column) is actually perpendicular to the two on either side (which are from the overhead viaduct).  Confusing isn't it!  It helps to remember that the viaduct is certainly not curved as shown in the panorama!

As always, you can click on the image to enlarge it.
