A good friend of mind, several years ago, sent me some pictures she took of the REAL Seven Bridges Road...the one that Steve Young wrote and the Eagles covered.

Here is a link to the pics. I thought she had sent more, but there is enough there to tell that there really is "moss in the trees".

Don't forget to left click on the main images. That expands them to full size and especially the first one needs to be expanded to see the moss.
