The guys on the videos make it look easy, but we all know that it's just not that simple. Sure everybody gets lucky and some guys are good, but deep down inside you yourself know just how tough it's going to be and we always prepare ourselves with the realization that we may go home empty handed.
Do your scouting well in advance and know where the turkeys are and where they are going. Then set up in those travel routes, put out some decoys and be prepared to stick it out. Don't do any calling to them prior to the season opener, that only educates them. You want to sound like the newest best piece of tail on the block when the season opens. Take a book and prepare to stay all day, I carry plenty of water, soda, snacks, and reading material for an all day sit when I'm blind hunting.
Put your decoys out like Wayne stated because more times than not the gobbler will at some point turn to face the jake nose to nose. Then when he fans out you can draw and send one right up the poop shoot. That's the best possible shot you can get with a bow, cause if your on your mark it will go screaming straight up into the vitals, if it's high you got a spine shot, and if it's too low you will send it right between his legs with no more than a few cut feathers and the bird lives to hunt him another day.
Calls are important sometimes, but I've killed quite a few big mature gobblers without ever picking up my call. I did my home work and I was in the right place for an ambush and let the decoys do the work for me.
Your best tool out of all the others is patience, you never know when this will be the day.
You also may want to think about more than one blind set up just to have a back up plan. I try not to put all my eggs in one basket. If you don't have or can't afford another blind, you can build a real nice one in a good spot out of available cover. Cedar trees, a pair of pruning shears, a roll of wire or rope/para cord, and some camo netting will rival most store bought blinds. String the wire or rope around 3 trees to create a "V" at about chest height when sitting, hang your camo netting over the wire/rope, then cover the outside with cedar limbs. I've constructed many of these in less than 15 minutes and hunted from them with great success. Only problem is they won't keep you dry, unless of course you have a big umbrella or get all fancy with a sheet of plywood for a roof.
Good Luck!
