A few of the many:
Ian Nelson, Jason Shoemaker and I went up to scope out the Warhorse line and climbed up Slip Slidin and then scrambled to the top of that buttress. I drilled the anchor holes, pounded in the bolts and ... brought the wrong wrench. Its not fun to rap off hand-tightened anchors.
Once, with Backclip we hiked all the way up to the west side of Westwind to do Grumpy Old Men.
Forgot the drill bit. Backclip took a nap while I went back to the car to get it.
Backclip suffered through my first attempt at aiding White Lines. Knocking off blocks and dust raining down. Took many huge whippers onto a piton that I should have tied off short but didn't. Bent the LA almost in two. The real gumby moment came the next week when I thought it would be a good idea to jug the fixed line. About 35' off the deck the rock behind that piton blew and I fell with the jumars on the fixed line. Very lucky it didn't rip out that rope - thank you very much Mike Libecki for loaning me his new Black Diamond ascenders!
Don't worry, the Smoot knows how to take a leader fall. But he also knows how to get back on the horse!
Oh, and I forget my harness at least once a season.
