well,it happened in my old yale heights/irvington neighborhood in baltimore...
..actually,it was jack`s old neighborhood,too...was a strong,lower middle class neighborhood when i was growing up....it`s pretty horrible as i speak...
drug store gone...food store gone...gas station on the corner gone..replaced by street corner churches and lotto joints...
i moved from the inner city when it became really bad... and the same thing happened in that neighborhood...
the issue of property values declining is pretty much true in many instances,from what i`ve experienced...
some high end businesses relocate....and are replaced by low end outlets and such....(in baltimore,hecht`s and j.c. penny department stores have relocated to the suburbs and have been replaced by the value city`s and dollar stores of the world)....
we saw downtown baltimore deteriorate to the point of almost becoming a ghost town....which precipitated the building of the beautiful inner harbor....
hard to judge the crime stats in b`more city...it`s been a very dangerous place for decades..other than the inner harbor,of course....
i`m sorry it`s happened..it`s just that it`s been been my own experience....
