At lunch time I drove down to the household hazardous waste drop off facility that Oklahoma City operates. I donated tow gallons of antifreeze and some brake fluid. It is nice that they accept the stuff that builds up at home. They take old florescent bulbs, batteries, paint, automotive waste like what I had and lots more stuff.
I just show them my water bill and they are happy to take it all.
They don't accept nuclear waste or old tires so I just stack that stuff in the back yard.
