I lucked into putting up a route in NC that has become one of the standards, and up on P4 there is a stretch of a solid 25' of slick ass insecure .10a water groove above an ehh, TCU and a sideways RP. The only reason I didn't drill at the time was because I was so certain that the climbing had to be much easier and I was just climbing horribly. For quite awhile after I'd get calls from guys asking permission to put in a bolt and I'd say fuck no and I'll chop it if you do. Maybe it should have been bolted on the FA, but if you come after you know two crucial things that I didn't: That it will go and how hard. That's a huge advantage. Most people that climb it now tell me that crux is the capstone to a killer route, and a bolt would ruin it.
