Dave,

Yeah, I don't know if that is a town / country / state requirement up there in BC, but its a pretty busy job site with all the equipment moving around and 40-60 people working at any one time... so they are probably a good idea!

Randy and crew are handling it like a commercial site (which it really is), even though its a volunteer / educational event.

Those truss chords are pretty amazing logs. The trusses are 44' long - and there are 4 of them. Can't wait to see them start to stand up!
