Though I have never had one walk right over me, I have had them mere inches away a few times...my swamp bird on the second day I hunted him was a Palm Fronds width away, my first bird was the same way but unlike my swamp bird, my first bird didn't know I was there,lol....
Last season scouting I had a whole group of gobblers and jakes that hung out around me for the longest time, within 5-6 feet at times and I was in bluejeans and a camo shirt & hat, lol....I was throwing leaves on top of my legs to try to cover them up, they knew something wasn't right but they still hung out.
My 1st Seminole Ranch bird was gobbling and we were making our way to him along the treeline, the next thing we knew that bird gobbled and it was right there above us, it must of turned around on the limb and faced us that time, we stopped immediately , waited for another gobble to make sure he wasn't spooked and took a few steps backwards extra slow like and waited for daylight....
I'm sure I can think of a couple of more times if I tried......I have been blessed
