using a ground blind would be a good advantage over a plain old brush pile
Yes it is a good advantage. Is it totally necassary, NO, but it sure makes getting drawn without being detected a whole lot easier.
where does everybody shoot a turkey with a bow
Broadside shot=at the point where the wind attaches to the body. rear end shot=at the base of the tail feathers, and lastly, facing you shot= base of the neck. Alos, if you are very confident in your shotting ability, you could take a head shot.
This is what expandable braodheads are made for. I like 1 3/4" expandables or higher. Good Luck!
