When I think of Missouri (and I do often actually), I think of a lot of things. Fishing, canoeing, Mark Twain and volcanoes. Oh, wait. I never think of Missouri and volcanoes, but apparently I should since I've now learned there were no less than 3 ancient volcanoes in the Show Me State.
One of my favorite comedians likes to joke about everyone talking about their love of hiking online. If you really do like to get out and really do hiking, you should know about Buford Mountain in Missouri. It's a rocky hike, but has a sweet view as a payoff at the end. Oh, and it's an old volcano.
