As of Monday, Oct 14, these mattresses are still on the curb. This site looks particularly bad.

As of Monday, Oct 21st, this situation looks seriously unfortunate and to top it off more mattresses were added to the pile further out. There must be 50 feet of curb trashed by this debris now.

This was one of the worst situations I've seen since reporting litter/graffiti and so it is all the more appreciated that it has been attended to, thank you to any and all involved in that.
