I basically understand how the addressing system works, starts at Michigan or Ford I think and ascends or descends from there, same with Woodward and John R. I live near 9 and a half and Dequindre and the addresses top out at around 23800 before they end at Woodward heights, whereas on the other side of Deq. the addresses get up to 23900 or so before hitting Stephens. What is the reason for the difference of a hundred #s? The lot sizes further south?
