My favorite way to do it is in the auto parts store parking lot. They will help you cart your full drain pan back to their oil recycling receptacle and some will even prop the back door open for you to walk it straight there. The bonus being if you do happen to spill a bit you're not stuck having to power wash your own driveway. I've got a process down to where I can pull it off with one pair of nitrile gloves, one rag, and one trash bag, to keep any residue from the drain pan staining anything.
