I know right where they are, I live right up the street from them. I'm not sure what the membership fees are, but I can find out for you if you like.
This is a hot area, and it is hard to find property for sale in the Blackhawk Tennis Villas. If you want me to keep an eye out for you, just let me know.
Thanks Al and you have a Great Day.
