Last year, I took my first turkey with a longbow (or any bow for that matter). I sat in a blind all morning and never took a shot. One of the other guys in our group walked down to my blind and helped take it down. We were walking out to the cabin where we were staying and walked up to a large flock; ~70 turkeys. He shot one that morning so he stayed with the flock and I headed to a likely ambush point.
A large draw extended from an open grassy knoll where the flock was located to a broad, grassy valley. The draw passed through a cedar and hardwood-lined strip along the valley wall. I literally backed in to an eastern red cedar that stood by itself away from tree-lined valley wall.
I had a tom walk around the cedar to within 5 feet. I drew, he ran, I drilled him. He died 35 yards away from me. Full camo, headnet gloves, etc., but no blind.
Two days later, I tried to run and gun with my longbow. I had two toms strutting at 10 feet on top of a grassy knoll while I was laying on my belly. I could not get turned to try a shot from the ground. This is a shot I have practiced after watching Fred Eichler and a few others execute it. Ten yards is very do-able, let alone ten feet.
I was able to get to a knee after spooking them and overshot one standing still broadside. Mis-estimated range at 20 yards; I thought 25 and overshot.
I will continue to hunt turkeys from a blind for a while, but it is not necessary. It is an absolute blast running and gunning with a bow. You may want to try practicing shots laying down and from just about any conceivable position. Find out what from what positions you can shoot accurately and be ready when the opportunity comes.
As for this year, my turkey season ended before it started. I had cervical fusion surgery on my neck about 2 weeks ago and cannot shoot a bow for about another 1 to 2 months. But next year I will be back and chasing turkeys ouside the blind! You should too!
