> Red Rocks, A Climber's Guide, by Jerry Handren. He's British yes?
Scottish - still British, at least for the moment!
Paul Ross? He's done hundreds of new routes in USA but has he published guide books to 'em? If not he must have had a big hand in on-line info, most recently for San Rafael Swell, I would imagine.
I've only been to New York City once, in 1989, and was simply doing a 2 day tourist thing after a few days at The Gunks. This naturally took us into Central Park where we gravitated to a rock outcrop and were surprised and delighted to find some guys bouldering - turned out to be Rat Rock. They even lent me shoes to have a go.
