From Dave Brigham:
This is about the most well-lighted tunnel I've ever seen. Located in Brookline, Mass., the Clinton Path underpass allows travelers to cross from Beacon Street toward the Fisher Hill neighborhood, under the MBTA trolley tracks.
For more about the path, read this short article.

Now, as for the title of this post. It comes from one of the touchstone movies of my life, "Monty Python and the Holy Grail."
