I found this list of best beaches via Audrey Scott and Daniel Noll at http://www.uncorneredmarket.com/ Since I’ve been to only a few of these, it tells me that I have lots more beaches to explore.
My own list of favorite beaches can be found here. Five great reasons to spend more time at the beach and the professional beach bum code of ethics can be found here. Life is short. Get yourself to a beach asap.
