Camo is for the hunter more than the deer. I have found deer in Iowa much less suspicious of everything than in Mi,,where I came from. Even less cautious if you hunt a cattle ranch, where the deer are seldom bothered,,as I have related numerous times on here already.
Sat on a pail, in the open,, in ankle high grass, with some sticks piled knee high and 2 yr old bucks/ does with fawns,,paid me little mind. Being still,,no quick moves, is most important, nomatter what you have on. That being said,,I bought "sticks and Limbs", camo for the west trip and still use it today..Good for ground or tree.
