I always like getting to my area at least an hour before shooting light. I also like to park in avery obvious location, polite hunters will go find another area. I then walk in to an area near where I think the birds are roosted and follow cpacs advise. There are several benefits to this.
One you beat the competition.
Two it is early and I do not think turkeys can see well in low light. Your movement sounds could be a deer or coon or other night critter to them.
Third you are sitting and quiet for a long time before you make your first call.
It is worth sitting there for an hour if you want a bird.
