Davies Plantation Homeowners Association

I live on Gypsy Cove. about 10 minutes ago an African American male looking to be in his 30's rang my doorbell and asked if this was the 'Jones' house. I told him no. He said he was lost. I asked if he wanted to be on Gypsy Cove and he looked puzzled. that made me suspicious, especially because he had been standing w/ his hands on my front door looking into my house when I answered the door. I am not sure if he is casing our homes but please be cautious. he is driving a white, fairly new model car.
