Beyond that, the whitetail world is changing fast this time of year. Early reports indicate a good mast crop in the region, and a few acorns are already falling. Aside from the rut itself, few things shake up predictable deer patterns more than a heavy mast crop. And, although most bucks in the region are still holding on to their velvet (including the bachelor group in the trail cam photo above, captured the last day of August), a few are beginning to strip it away. The rest will be done within 10 days. When the velvet is lost, the clockwork patterns of a summertime bachelor buck usually go with it.
