On big, serious routes (Dreamcatcher, Jumbo Love, etc), who puts the bolts in place and how? Are the bolts there before the "first ascent" or does the first ascender put them in place as he goes? It seems ridiculous that he would be carrying whatever equipment it takes to do that with him.
Who decides how the route will go and where to place the bolts? How could they know before the thing has been climbed whether they're putting them in good places, route-wise? The whole thing seems very confusing to me.
