We probably do have mutual friends (as nearly all NYC Jews do). I was married at Sha'are Tovah synagogue on Abingdon and Lefferts. The only other FoxPro programmers in our area that I know, though, are Daniel Taller, and a woman named Bloom (I forgot her first name); I had a couple of Shabbos lunches with her family a few years ago. She lives in KGH, around 75th and 141st. A while back, Daniel Taller told me about a software company that uses FoxPro, and is located on Yellowstone Blvd.
I Daven wherever my Shabbat hosts do, most often it's at Etz Chaim.
