The mountains are calling and I must go, and I will work on while I can, studying incessantly.

Mountaineers Cory Richards and Adrian Ballinger are back on Everest.
Armed with Snapchat and a whole lot of experience, the duo is attempting the peak (again) without oxygen. UPDATE: Just before 11 am on May 27, Adrian Ballinger and Cory Richards summited Mt. Everest. The climbers left Camp 3 (located at roughly 27,000 feet) the night before, staggering their departure times; Ballinger left slightly ahead of Richards, since the latter had been climbing quicker during the preceding days.
