Wat he said, dried paint can be disposed in a municipal landfill. Where I live an individual household can take up 30 gallons of paint to waste collection events, no commercial disposal is allowed at these events however.
Just take the lid off and let it dry, or as stated, if it is too much, add the drying shit too it and toss it in the normal trash.
Or, paint some joists in the attic to get rid of it.
Depends on your county. If you're in Dallas County, the recycling center is not far from Plano Rd and 635, and they do check ID to verify you're a resident. Easy to do though, you just pull in the lanes, and the workers pull it all out of your car, you never even have to get out.
In Euless we just pull the lid and let it dry out (or add litter / drying agent, as mentioned), then put it on the curb for normal trash collection. They recommend leaving the lid off so the disposal company knows it's dry.
