I'll be coming in on June 18th. First time for me, although I did complete the Marine Corps Summer Mountain Survival course up in Bridgeport, CA....in my younger days. I should be acclimated by the time I get there. I'll be spending 3 days the week before in the Tetons, then plan on spending a night up at Devils Postpile, and the night before at the Portal Camp ground. Trip of a lifetime.
