its one of thoes long, skinny lots.  I hate thoes, it's the least useful way to plot land.  Just a way for the developer to get the most houses on a street, and sell big ackerge (SP?) lots.  though 13 is nice.  I looked at  a house that had 3 acers, the lot was 50yd wide and went very deep from the street.  not useful at all, it still had neighbors like it was on 1/2 acker
