Join the Vail Symposium as they welcome Explorers Grand Slam world record holder Colin OâBrady for a free Unlimited Adventure program presented in partnership with the Vail Public Library tonight at the Donovan Pavilion. There will be a reception at 5:30 p.m. and the program begins at 6 p.m. The Explorers Grand Slam entails climbing the highest peaks on all seven continents and trekking to the last degree of latitude at the North and South Poles. OâBrady astounded the mountaineering community world-over by finishing in 139 days. Space is limited and early registration is recommended by visiting VailSymposium.org.
