There are many ways to tell if you are in the ghetto. Other than hearing "Get the F^@k out da Hood!" screamed from passing cars.
Shoes hanging from telephone wires from above.
upside down signs that in a nicer neighborhood would be fixed weeks ago.
Always a sure sign you're in the ghetto when instead of guitar lessons being advertized on telephone poles it is a ride to the local prison to visit relatives.
And if you miss all of that just count the number of random shopping carts around where there is no grocery store in sight. The higher the number the more ghetto the street.
