If either of you was really "stunned," then you haven't climbed at Pinnacles as much as I thought.
Yes, the first ascent party on that route and several nearby had a bad habit of using poor quality hangers, or leaving them off in some situations. In order to avoid repeating the word "hangerless" in the new book, I've been replacing those in particular with new 1/2 inch stainless steel. The hangerless fifth bolt on Peon's is the only one in that area that I haven't gotten to.
Did you even notice that the first and third bolts on Mission Impossible (listed as "hangerless" in the new brown guidebook) were new? If you found a bolt at the base, it wasn't from my replacement of either of those two - I took the removed stuff with me from both bolts and didn't drop anything. I also patched the old holes to invisibility. And if that route's sixth bolt really is missing, then that's new as of the start of April (it was there as of April 3).
As to "reimbursement" for your leaver 'biner? No, the guidebook author isn't' responsible for that. In fact, you owe him double its value for being too obtuse to walk around to the top of Whitetail to rap off and inspect the situation (so you could report here more intelligently) while you retrieved your gear. I'll take my payment in beer. And no, nice intentions that didn't work out yesterday don't count as payment. You still owe me.
