I solved this same problem at a cost of $3.50 per board in my garage. I simply bought 60lb rated, screw-in utility hooks and screwed them into the rafters in my garage. I hang the boards from the handle of their board bags. They are out of the way, and I can put them up or take them down in seconds. Also, they only need one mount point, and boards can be hung inches apart. You can even stagger boards on different rafters to save space.
One tip for anyone starting a “hang ’em over head in the garage” project: Make sure that you have the garage door open when you mount the hangers. Then also make sure that your longest board will fit before you start drilling.
