© Daniel HuffmanOne of my dreams is to put a canoe into the Missouri River in Kansas City and float a few hundred miles down to Columbia. Maybe it will happen, maybe it won't. But these "subway-esque" river maps by Daniel Huffman make it look so easy. A trained cartographer, Huffman focuses on the Mississippi River System (which includes the mighty Missouri) in the map above. Check out more of his spectacular cartography here.
