I am unfortunately in that group of souls that have a long commute. I can't control where my great job is, but that doesn't mean I like spending so much time in the car. To pass the time, I look for interesting podcasts, and I've stumbled on one that has me fascinated. Dan Carlin's Hardcore History is pretty amazing.
Unlike most podcasts, HH is incredibly detailed. The latest, Blueprint for Armageddon I, is over three hours on the events leading up to WWI. I've spent some time reading about WWI, but I learned a ton of new information from this podcast.
I'm now getting through "Death Throes of the Republic, Parts I-VI". I've only made it through part I so far, but it's fascinating listening to all the details that lead to the fall of the Roman Empire.
So, if you're into history, and you have some time on your hands, I recommend checking out Hardcore History.
