#BikeNite A8 milepost 7 on SE Stark, seen here via #BikeSummer group ride ( shift2bikes.org .) We visited four of these cut stone markers (circa 1850, nothing but a letter P and the number chiseled into it.) This one has a sign explaining, many of the others have fallen, to... you guessed it: cars. #carsRuinCities (We rode out via winding side street routes, as Stark is obviously a car sewer. #pdxBikes)
