Congratulations on the summit, and congratulations on the engagement. I hope your life together is long and memorable. Anyone who can plan and succeed on such an adventure from across the country should be able to persevere through anything.
Your living practically at sea level is actually no different than most Californians who climb Whitney. So the altitude experiences are really quite similar.
Thanks for the note about the water on the switchbacks. It usually dries up or freezes in September. It's source is a snow field farther up on the mountainside.
