As far as the Arrow bolts are concerned-- I think the basic history (not that I was there...) is that some Gunks developers were okay with the occasional protection bolt, in line with traditional climbing development in many other areas around the country. It wasn't just Crowther; Dick Williams installed several bolts on Gunks climbs over the years. I think some folks disapproved but there was not a war over it because the community was small as was the number of bolts. It went to a different place when the fear arose that a new generation of climbers would put up a whole bunch of super-difficult lines protected by lines of bolts, as was becoming the norm in other areas. The specter of this sort of development is what drove the debate and eventual ban on bolts.
