Few people haven’t heard about the ancient city of Persepolis, which lies at the foot of the Mountain of Mercy (Kuh-I-Rahmat). In ancient times, Persepolis was the capital of the Achaemenid Empire. Regretfully, it was burned by the Greeks in 330 BC after they looted the immense treasure of this city. It is said that Greeks needed 5,000 camels and 20,000 mules to carry all the treasures from Persepolis. The only thing of Persepolis that has survived the wear of time is the ginormous stone terrace 530 by 330 meters adorned by elaborate stone sculptures. It is amazing how intricately detailed some of the sculptures are, despite the fact that they were created many centuries ago.

If you were to meet this guy in the woods, especially if it’s nighttime, you’d probably think that it’s a local troll or a yeti. However, in reality, he’s no yeti. His name is Mick Dodge, and before deciding to live in the woods, he was a marine for six years at Fort Lewis. It is hard to tell what moved him to leave the busy life of the city and start living in the Hoh Rain Forest. It could have been that he decided the leave the stressful life of the city, or maybe he simply loves the solitary life of a hermit. Another thing that is peculiar about Mick Dodge is that most of the time he walks barefoot, hence the nickname “The Barefoot Sensei”.

Dunnottar Castleis a ruined medieval fortress located upon a rocky headland on the north-east coast of Scotland, about 3 kilometres (1.9 mi) south of Stonehaven. The surviving buildings are largely of the 15th and 16th centuries, but the site is believed to have been fortified in the Early Middle Ages.
