We've had every other sort of bike-related thread. Time to discuss your epic climbing rides. Whether it be some single monstrous hill or a whole ride that you swore was entirely uphill -- let's hear it. Feel free to enter multiple times.

I'll start the festivities with the Mt. Washington Hill Climb. I was stupid enough to do it twice. Most people learn that that much suffering isn't worth repeating, but I'm a little slow. 7.6 miles, 12.7% average grade, final 100 yards are somewhere over 20%+, about a third of the road is dirt. Throw in the horrific weather Mt. Washington usually experiences and it's truly a suffer-fest.
My first year I made it up in 1 hour 40 minutes. Absolutely zero visibility at the top, with the wind in the 20mph range. I was soaked from the fog, shivering from the cold... It sucked, big time! It was so foggy at the top that I never saw the last hairpin turn -- I wound up getting caught trying to navigate the turn at an awkward angle, and I tipped over about 50 feet from the end. No way was I getting started on a 20%+ grade, so I just walked over.
My second year I made it in 1 hour 35. Practically no wind, not a cloud in the sky, 40-some degrees at the top -- about as good as you're going to get, weather-wise. This time when I reached the top somebody stepped out of the crowd in front of me and I was forced to stop or run him over. I chose to stop

: and walked across, AGAIN.

: Truth be told, I'm not sure I had another 100 feet of 20% in my legs, so who knows if I could have made it after all.
I did discover something interesting though -- the first year (when I couldn't see my front wheel in the fog) was actually mentally easier because I couldn't see a thing. You don't know what's coming up. Just soldier on, it all looks the same. The second year was nice to look out and see the view, but every time you looked up, you saw exactly what was coming up which is really depressing!
