ash,

Of course you dont have to call in the bird by yourself!
That is one of the greatest things about turkey hunting, you dont have to go alone, I hunt by myself maybe 3 times a year, the rest are with family and friends!
If you know a experienced caller, what better way to learn than to go with him or her?? Its a great lesson! Also, dont be afraid to ask questions!!
Some tips might include, letting your poundage down so you can hold your draw longer. Also, set up brhind a tree instead of in front of it so the tree can hide the movement from drawing your bow!
Please PM me if you have any more questions!!!

Good Luck!!!!
