That's always a good idea, too.  There is also the [url=http://www222.pair.com/sjohn/blueroom/plots.htm]Big List of RPG Plots[/url] that you can use as a plot-generator: just roll the amount of plots (33-34) on a roll generator twice.  The first one you get is the 'hook', the second one is the 'meat'.  The plots are extremely generic so that they can fit any world or situation, and the writer offers some nice twists and curveball suggestions under each plot.
