Here in New Hampshire, there is no NEDT and no PaintCare. Massachusetts has NEDT, and Maine, Vermont, Connecticut and Rhode Island have PaintCare.
New Hampshire has the parking lot trash can at your local big box store, where the paint was purchased ........ no, wait ..... NH has the paint swap system, where you take your old paint down to the local store and trade it off for some nails or groceries or ..... new horse shoes for the horse from the horse shoe-er. ....... Can I git mah horse a new set of shoes in exchange for thiisy here can of paint, sir? ......
....... or, being more 2019 here ..... maybe the local car repair will replace all four tires on your car in exchange for some old paint!
