We hired a different crane company to help put up the rafters- it went so much better, the difference was unbelievable. https://loghomejourney.wordpress.com...new-crane-guy/
Blog post about getting the Ridge Pole up. Learn from my mistakes: have the crane set the RP up on the RPSL's, MARK IT, then take it back down and cut a nice big flat spot where it will sit on the RPSL's. Also spike it with 2 pieces of rebar, instead of just 1. Anyway, enjoy!
