Try making some bear crack a few hours before hand at the sight, the smell of it might make them come in sooner.
Or, get a bear call and do either a mating moan or challenge, either one may make the dominant bear come in earlier and give you a shot.
I've been baiting up in Idaho for a month and haven't even been hit, I'm sure my bait is sent free by now and most of it is gone to other critters.
You baiting in Utah?
