There's something pretty cool about the shape of the Miami-related sprawl when you pull it out to an appropriate distance. I'd been interested to know what, if anything, is legally or practically preventing the city from just expanding further and further west if anyone happens to know.
UPDATE: Yes, yes commenters I know it's a freaking swamp but there's plenty of development on ex-swampland in Florida -- hence all the canals and weird-looking lakes.
