Squatter's Camp on Fifth Ave?

From FIPS reader Diana:

"I have lived in the Slope for a decade and have noticed a few, uh, rather perpetually low-end, down on their luck storefronts on 5th Avenue (particularly between 4th and 9th street). But this one seriously takes the cake, and has profoundly perplexed me (its located between 6th and 7th St.'s, I think).  This, apparently, ungentrifiable patch of Park Slope decrepitude seems like something out of Grapes of Wrath, rather than trendy 5th Avenue."

Gotta say, we're in total agreement with Di: that place is fucking disgusting (though Kook should probs get his ass down there pronto, as that's a nice piece of graffiti real estate ass). If I wanted to look at shit like this, I'd just move to Williamsburg.
