What’s That Sound?

I have a riddle for you:

I can smell the sound. I can taste the sound. I can see the sound. I can feel the sound. But I cannot hear the sound.  What sound is it?      (answer below)


My son James is 5,000 miles into a driving trip in his 1999 Oldsmobile 88 out to the west coast (Rock Springs WY, Salt Lake City, Lake Tahoe, Los Angeles, Fresno, San Francisco, Sacramento, Portland, Idaho [for the Eclipse], and Washington State.). Today he is in Port Angeles awaiting the ferry to Vancouver Island, in British Columbia. He said it was fun to buy a ferry ticket and need to show his passport.  It got us talking about the body of water that lies between Seattle and the Olympia Penninsula.  Oh, the answer to the riddle?… the Puget Sound.
