It was all change in Key West in 2015. The biggest story of 2015 (officially, according to a Florida wide poll) was Florida gay weddings - the very first of which were conducted right here in Key West. Just after midnight on January 7 2015 (as soon as it had become legal in Florida) on the steps of the county courthouse in Key West. Watched by a good sized crowd who wanted to be part of history being made.
Keeping with gay, later in the year on 29 May 2015 a "gay" (i.e. rainbow) crosswalk was installed (painted on the road) in the gay block (Petronia Street) of Duval Street. I think this is a most excellent idea and as I believe they are permanent, I look forward to seeing them when I visit later in the year. They gained lots of international media coverage.
Now to the major themes running throughout the whole of 2015 in Key West. According to my radar, in order of strength of signal, I would say they were:
1. Key West is going to the dogs. Typified by talk like: "Woe is me, Key West is getting busier, very noticeably this year, especially with all the tour buses arriving for the day. Key West isn't what it was, the homeless have taken over..." etc etc
2. Tree commission is out of control and literally killing Key West's natural heritage
3. More new building development hits Key West. In particular inappropriate construction approved in Old Town.
