I think I'm 16 for 19. Two of the "failures" happened on 48 hour monster hikes. One started at Mineral King and when I hit the spur trail to the summit it was snowing so I keep going down. Two years later we started in Kings Canyon and came across Avalanche Pass. I was so wiped out when I hit the spur I didn't even think about a summit attempt. One year back when I was on the USS Constellation we deployed mid March and returned early October. No hiking for me, but 36 hours after we pulled in I was at the Portal. I was dragging all morning and by the time we hit Trail Camp I had "violent diarrhea". That year was the only year I never made it to the top. The other two years I had already day hiked it or returned to day hike it a week a later.
All great hikes (except getting sick), just no summit. No biggie.......................................DUG
