Very tough critter to hunt with just boots, I would think calling is your best bet. I've been hunting since I was 18, now 45, and I've only killed one. Maybe seen 5 in my hunting life, and I have spent many hours, days in the woods. I hope you kill as many as you can, they eat a lot of deer. I got lucky when I killed my only cougar, I was in a tree stand hunting deer and it came in and layed down.
