Okay, I'm sure ya'll have figured out by now that I'm rather infatuated with the idea that dragons were, at some point, real, and quite possibly still are.
Discovery Channel apparently feels similarly, though in a rather more "Evolution did it" sort of way. Their special looks interesting, though...
http://animal.discovery.com/convergence/dragons/Since I don't actually get any sort of TV, odds are I won't ever actually see the show, but the site itself is still pretty interesting.
Interesting how many of the ideas their "experts" came up with, I came up with on my own...
Methane powered flight, + eating rocks (sparks) = fire breath! Whoo!
