Parasitic Drain? Help?

Where do I start when I'm looking for a power drain that is draining my battery? I took 1st year automotive, so I know a bit about electrical, but still pretty new!

First place I would start is with anything aftermarket. Does it have an aftermarket alarm, stereo, amps, gauges, lights, ect...? If so, look where they pulled the power source from for each item.

Put an ammeter on the battery, pull one fuse at a time until the drain goes away or greatly reduces. Start with the obvious circuits as 5-Speed mentioned.
