agreed on Denali. god forbid you came up the muldrow. that practically starts at sea level - something like 18k gain or something absurd like that... you could theoretically climb st elias from the beach, but i think most folks get flown to 10k or something... just thinking off the top of my head, don't hold me to it!
course, san gorgonio always gets my respect - especially for a dayhike... sea level for breakfast, 11k for lunch, back to sea level for dinner... always screws me up.
