kyotee are u sayin chain the trap to something a yote could drag??? sounds interesting.
I didn't use drags, 2-prong made out of either 3/8" cold roll or rebar and have the points bent in opposite directions, until the gov't hired me to do depredating coyote work for the state back in the early 80's.
It really depends upon if you have the type of brush, saplings, cover where once the animal is caught and pulls the chain and drag from under the trap, it will go a ways before getting hung up. Sometimes I would find a good location and hook the drag on a couple of saplings or brush within the set location but 5-6' away and hammer the chain in the ground up to the point of the trap location where the trap was buried. Coyotes and other species see and smell iron and other metals/smells all the time, and a piece of iron sightly sticking out or hung-up somewhere isn't going to alert them. But having any portion of the trap itself exposed, it moving or wobble when stepped on, only puts that animal into 'cautious' mode and/or makes them dig. This is something, once you get a digger species or one that has associated a particlar smell with a trap snapping or something out of place, you usually will have a problem animal to catch.
