I agree with his tactics 100%:

15-20 lbs of corn in a high traffic area and hunt it 2 days later after adding (throwing) a few pounds to freshen up the corn scent.

Mature bucks around here will not come to corn during daylight. I just don't get sightings/shots/cam pix of them at corn - period.

We use the tactic to get young/old/new hunters a shot and to deplete the doe population.
