I did my first october challenge only last year and completely loved it.
So for this year, I picked "road trip" as a theme: a trip through the US. Start in Hawaii and then state by state (Washington, Oregon, California, Arizona,...); 1 movie set in each state and then see how many states I can cover in 31 days.
So far I have mostly been going on things like "the united states of horror":

How reliable are those things and are there other/better sources I could use?
