That is one great collection of calls CM.
My first was with a plastic Olt, after a few years of on & off trying, I saw a coyote out on a powerline while grouse hunting. I sat right down, slipped a couple of #2's in my Win 21 skeet gun, called for a couple mins, then shut up & waited, like I would for a turkey. He showed up & I clobbered him. Mangy, half his hair gone, stunk, some trophy. That was in the mid 80's. Hey, maybe I should try and shut up a little now?
