I am hunting a spot with my two cousins this sunday (Its their first hunt ever, and I am determined to get them addicted to bowhunting

).
Now, I am aware that the best time for human activity during the day is when the sun is at its peak. But when do you all go into the woods in the morning? Every time I've hunted early AM, I've always screwed it up. I have a spot where I am pretty positive there will be a ton of AM activity, but I dont want to get there to late and spook them when we set up. Our legal hunting hours are 1/2 hour before sunrise, to exactly sunset.
thanks,
Jake
