We experienced Islamorada (that's where we stayed), plus Key Largo and Key West. Everything was lush and spilling over with flowers and southern hospitality (see that pineapple?). I didn't know that roosters roamed the streets of Key West (and even sneak inside the shops)!
Being someone that loves formal gardens, I was thrilled with all the perfectly trimmed hedges. I also loved the bright colors, stucco walls, fancy gates, and just general quaintness. We even got up bright and early the first day to see the sun rise...look at that. Just imagine a soft, warm breeze.
Many parts of the keys still have that 1950s-1960s aura...adding more mystic. It's just an amazing place surrounded with great history, expanses of ocean and lots of sun.
