"My building is dog friendly. It seems like most of the people have dogs and love to walk them. We all clean up after our dogs. There’s poop bags in containers around the building with a place to dispose of them. There is also a dog park on the Key. "

"I don’t have dogs. There’s a very nice dog park right next to the green field. Dogs are not allowed in the field, that is why they have their dog park, but the many owners don’t follow the rules which is very annoying. Most of all when you get the smell when exercising...."

"If you don't have to commute out of the island it's wonderful. Otherwise, every event causes so much traffic. Living on an island is a blessing but the peoole really don't say hello or even make eye contact at the stores or parks :/"
