A snapshot of Mark Jeffrey jumping at Joshua Tree desert at night. Mark told me on CryptoTwitter that he visited there a year or so ago for the first time and loved it. It is VERY hot though in the summer. People don't come out until night during the hottest months. And skies are super clear. Very easy to see the Milky Way!
