Aside from the writer of that article apparently skimming Hollywood and thinking that Bukowski was Barbet, he doesn't seem to know what he's talking about re: Venice. I don't know when he lived there, but the area where Hopper's house sits is hardly the hood.
25 years ago the area was definitely hood-y around Oakwood, and Brooks almost all the way down to Electric was a mess. But the Venice of today is about a million miles from what it was back then. I went to Hopper's house once - around...1989? - and it wasn't even really a sketchy neighborhood then. But I lived in Venice at the time and maybe I was just used to it. His place stuck out back then because the houses around it were still old for the most part, and even the places that had been fixed up sort of kept with the old Venice Beach style.
You can hardly find the Venice of 20, 25 years ago anymore (not that you'd want to, I suppose). It's been taken over by the wealthy, but then everyone expected that would happen eventually. To describe any part of it now as truly dangerous though is kind of laughable. Comparing it to the parts of town that still are actually dangerous.
Blah blah blah.
