Are you serious about those crack dens??
Well, perhaps more like really grungy apartments in the area, some of which are rented to crackheads. Take a walk on the north side of the street, in the alleyway behind the shops, and look at some of the apartments there. Pretty awful looking. Really sketchy. Or at least they were previously. I haven't looked this year.
That mall right beside Haven on the Bluffs also looks pretty horrible, and it's right in front of the public school I mentioned, but it seems things are changing. For example, the Ikki Sushi moved out of its building on the north side and into a spot in the mall on the south side right beside Haven on the Bluffs. Not sure why they vacated the old spot. It's a pretty decently large chunk of real estate though so perhaps someone might put another condo there?
P.S. I find the above picture amusing, because the other business owners in the area were pissed off with them for not cutting the patch of grass in front of the restaurant (out of the frame of the picture above). It made the place look like it was "in da hood" with 1 foot tall unkempt grass, along with the weeds all over the place including in the cracks of the pavement. WTF. (That sign didn't help either.) Because of that I have never eaten there and probably won't eat in their new location either. If they can't be bothered to even cut the grass and kill the weeds, who knows what other corners they're willing to cut.
EDIT:
This is the mall I'm talking about. Notice the apartments on top. I wonder if the naked crackhead knocking on the public school window came from one of those.
You can see Haven on the Bluffs on the right.
