Hello and welcome. You are right in that there are not a lot of people of color here in The Villages. But my experience has been that most are open and friendly. Of course this experience is that of a white woman with blonde hair so I'm not sure how meaningful it is. There are two African-American clubs listed that you may want to check out. There are phone numbers listed so, if I were you, I would call and get a feeling for what others' experiences have been. There is also a singles club run by a member of this forum named ChaCha. (I'm not single either but it seems like a fun group of like minded people)

Hope you like it here. Good luck in your search.
