Oats ripen late in that part of the country: September - October. No one ever shot a bear in the spring that I heard of.
Really! Spring is when they're most hunted here. Although the principle is the same - we nail them around food supplies.
Cutblocks are a favorite here - they get into them to eat the new growth, bugs off the rotting wood, etc. They move a lot in the spring to replace lost weight from sleeping all winter.
People do shoot them in the fall, but most of them are shot in the spring.
