Well, on the plus side. My wife and I lived about 4 blocks from Pienza and saw them develop that area.
We really liked that area of Ranch Bernardo, even though it is not as desireable as many other RB areas such as homes around Bernardo Heights Country Club (where we also lived previously)
The weather is fanastic in that area. We only ran either AC or heat about 3 total days per year.
I love that Lake Poway park that is only about ten minutes drive to the East. When I was in good shape I used to drive over and fun full speed up to the top of Mt Woodson and then run back down to Blue Sky Ecological Reserve, about 9 miles. That was a great run, really wonderful.
