There are lots of threads on here about calling in animals, some in the bear forum too. Take a look around you will find plenty of info..
a few tips..
remain still
have some sort of decoy with movement so the animal focuses on that..(feathers on a stick, etc)
with bobcats, you dont need to worry so much about your scent as you do movement..
be patient...they are not like yotes...
have fun most of all. Good luck! Never hunted the hancock area, so, I cant help ya there.
