How To Discard Used Motor Oil

The subject says it.
Anyone have advice for the disposal of used motor oil - other than using it to preserve wood?
Thanks

I am told that there is a company that makes rounds to the various automotive service centers to pick up used oil for recycling. I have been assured by our mechanic that they dispose of our used oil responsibly. You may consider taking it to one of the many mechanics along the road out to the airport and inquire with them about their disposal process.
