Where does Route 6 start or end?

Anyone that lives on or has visited Cape Cod knows about Route 6 aka the "Mid-Cape highway".  Everyone also knows that it goes from the Sagamore Bridge to Provincetown but did you know that Route 6 was actually one of the first trans-continental highways built in the US?  Yep, it goes all the way to California.... and during a recent hiking and photography trip to the Sierra Nevada mountains, I found the other end of Route 6... :-)  The western end is located in the small town of Bishop, California near the Nevada state line.  Here's a self-portrait of me by the sign... it's only 3205 miles to Ptown!!!
