I used rebar about that long year before long in red clay and finally got my stakes up by hooking the z71 to them. I guess it all depends on the soil. Hard for me to trap, lease is 30 miles away, and I only set them out when I or one of my buddies can run them first thing a.m.
Post some pics next time you check Don, I need some motivation to get out and thin yotes at our club. Only caught grays last time, no yotes. Would like to set up on a cat or two though too. I need to order some dirt stakes first.
