where the hell am i?

i, like the city of duluth, have a bit of a neighborhood obsession. i grew up in southwest suburbs. for like 6 or 7 years, i lived in eden prairie. they don't have neighborhoods - they have housing developments. before that i lived in wayzata with one near-by neighbor, so that doesn't count either. before that, i lived in duluth. when i moved back up here, i always knew what neighborhood i lived in (usually east hillside), but now i'm not so sure. i live at 4107 w 4th st. i thought this area was called denfeld, but when i say that, people are like, "you mean by the school?" so somebody tell me what neighborhood this is.
