I say set up the decoy,bring the bleat can and use some estrus scent on the decoy(if it's a doe).If the rut is on it shouldn't take long before you have a buck within arrow range.
You might try to set up the decoy about 20 yards to your right
(bucks will come up behind a doe decoy)or 20 yards to the left if it's a buck decoy( face to face to a buck decoy).
