Im in Calgary, Alberta. We have a fair number of yotes up here and ive been at it for quite a few years and have improved my technique and gained more knowledge each time out. as well, my relationship with the farmers and the access to a large amount of private land i have helps alot. Other than that, i just get out alot and put in my time.Ive perfected my calling, shooting, and snaring techniqueover the years. I assume your somewhere down south so dont think your doing anything wrong with only 13. Thats a decent number of yotes and alot dont get that many just shootin. Good luck and happy huntin!
cheers
