"Best tatics for consistently kill'n yotes", thats the hard part, but my best guess is time in the woods would help more than anything.
Go buy a couple mouth calls & start practice'n, just like hunt'n anything else ya have to be in the woods to find out the rest.
If your entirely new to coyote hunt'n go find a few DVDs to watch, Primos puts out on called Master'n teh art of predator call'n with randy Anderson, also thers one at eastern coyotes .com, they have a DVD thats shot entirely in the eastern part of the coutry, think'n mostly Alabama, lotta good info on it also.
