Low income part of Saint Louis County
, technically the Delmar Loop starts in downtown St Louis
and goes all the way out to West County
, but when people refer to The Loop
they mean the Delmar Loop (there are several other loops in St Louis, but they are referred to by their street names these days).
Rap artist Nelly is from The Loop, and he's proud. Same with the the St. Lunatics (I don't think they're all from the Loop, tho').
