If you haven’t been paying attention, then Monday, August 21 might seem like the end of the world. Temperatures will suddenly drop by as much as 25 degrees and the sky will become abnormally dark for being mid-morning. Don’t worry; it’s not the apocalypse, it’s just the Great American Eclipse. It’s been nearly 100 years since we’ve had a total eclipse travel from coast to coast, so this is kind of a big deal! While there’s usually a total solar eclipse somewhere every few years, it’s pretty rare to have such a huge portion of the population to have a good view.
