TRICKS OF THE TRADE

A Chicago 597 instructor Mark Duewerth has a Youtube channel it has alot of great info whether you haven’t done it in awhile or never learned, this information is useful and should be shared with everyone. It has videos about trade math,layout,knots,rolling offsets,rigging, and more. Check it out. I would like to thank Justin Clark from local 597 for sharing the info about his channel.  Mark Duewerths youtube
