Happy 100th birthday to the National Park System!  In celebration, we visit Dry Tortugas National Park with this guest post from our friend, Andy Stenz.  Andy is a photographer and blogger who I met many years ago when I first became involved in our local community of photographers here in Wisconsin.  He has discovered the beauty and warmth of Hawaii, and soon will become a permanent resident on the island of Oahu.  He loves to travel – – he’s now exploring Europe with his lovely wife, Jessica – – and was kind enough to share with us his visit to Dry Tortugas. Enjoy!  And be sure to follow Andy on Instagram…
