Here's a quick recap from a lifting and moving class at Ehove Fire Academy.  We had a couple hours to talk cribbing, airbags, prybars, driving wedges, and high-lift jacks.  It's not work when your having fun playing with blocks.  I did learn a new name for the high-lift from one of the attendees…a Sheepherder's jack.  I did a quick internet search and found that the predessesor of the High-Lift Jack Co. called them Sheepherder's jacks or Handyman jacks.  This bit of history dates back to the early 1900's.
