We call the building in your Fl pix the Iguana house. It is still the same since your pix. We were exploring several years ago with our skiff and checked it out. There must have been several hundred iguanas sunning themselves in the mangroves. Never saw so many in one place. The Keys have change a lot since Hurricane Irma, they really took a hit, but is rebounding back. Bahia Honda basically got washed away, it was shocking, looked like a sandbar, everything that was green was gone. Long Key is still closed. Knights Key Campground at the southern tip of Marathon right before the 7 mile bridge that I have been going to since I was a little kid is gone, its all condos now. Basically a lot of buildings that were not new and up to code are gone. 75% of the liveabords in Boot Key Harbor are gone, they still haven’t found a lot of them. My buddy had his 27’ with twins trailered and chained to a telephone pole in Big Pine. The only thing that was left was the transom and engines still chained to the pole. We were down in Nov. for the Offshore races and stayed at Curry Hammock in Marathon. I was totally amazed how fast the plant life has rebounded. Bahia Honda has rebounded nicely also. But it “old Keys” are gone.
