Give and Take
One man's lemon is another's lemonade, it is said. The very thing you're about to toss may be just what your neighbor's kid needs for his empty dorm room.
So if you have something that's still usable but not at home in your home anymore, think about giving the neighborhood a right of first refusal before you add it to land fill.
And if you don't get any takers, try Westchester Freecycle or one of the other Give & Take services in Westchester.
Here is one web address. If you used or know of others, please email them to me to include here.
