Where to get rid of dirty oil?

The local landfill here near Daytona has free "household waste" recycling, which includes oil, antifreeze, TV's, computers, paint, insecticide. etc. I like going there because they put anything that is usable on the shelf for the public! Of course you won't find all the brand names and variety of your local stores, but some "oil dump" trips have been more than worthwhile as I've saved money on trailer and home painting projects and found some automotive oils & chemicals, sometimes in still sealed containers.
