Actually, (believe it or not) the furniture thing used to be a lot worse.  Then UMD started offering furniture pick-up and it got better. Not a lot better, but better.  BUT for some people, unless you go to their house, hold their hand, and move the furniture for them..........ain't gonna happen.  I've noticed the lovely blue couch ensemble on east 8th and 19th also.  If you want to know who owns a property, look them up on the City of Duluth website under the city assessors office (you can look it up just by address).  That gives a listing of who owns the property but not a phone number. In the past when I've wanted a phone number for a landlord, I call housing inspection/rental licensing #730-5300, see if they can help.  Or if you want to vent to UMD, give their Facilities Dept. a call (they pick up the furniture.)  The DNT listed that number last week as 726-8262 but it said the deadline was June 1st for pick-up.  I would say your best bet is with the landlord of the property.
