small world thing

When we bought our first house (Annette and I) @ 18 years ago, we moved to the country outside of Jackson, TN.

The funny thing about this is we are catholic and the rural south has few catholics. Our neightbors then (the two houses south and the one house north) were also Catholic. So in the rural south, you had 4 houses in a row with Catholic families. ALl of us attended the one Parish in Jackson, TN, St Mary's.

What are the odds?
