Kurt and Mo: Thank you for your comments.
If pull-out is the reason for discarding the Duckbill anchoring method, I wonder if a larger model would overcome that. The largest Duckbill model is about 12 inches long. A second line of “duckbills”, also by Foresight Products, is called Manta Ray, and is made for increased resistance, installed with hydraulic jackhammer. There are also options for stoney soils (ductile iron, hot-dipped in zinc, rather than the standard aluminum). However, searches of company websites, and telephone contacts, have been short on pertinent,applicable value in my recent efforts. The thought of trying to put auger-type anchors in my stony land does not appeal to me, and driving posts has never attracted me either. Channel iron does seem worth trying, but I am hoping to find something I could get really excited about.
