Hmm.. interestingly vague description of the subject matter. "any park in the United States". I find myself wondering if zoos could be shoehorned into that description, I mean my local one is owned by the local forest preserve district.
Very cool. It'll give me an excuse to check out some local parks and preserves and such I haven't been to. I'm not well equipped for either wildlife or landscape photography, but what the heck.. they don't want much resolution, so I might be able to get away with some heavy cropping or crude panorama stitching.
