I think she was just stating the tag is in rifle season. Which is all of Sept.

Bear hunting in Colorado is either spot and stalk or my preferred method of still hunting (sneaking in close) over natural food areas. Scout the area you plan to hunt for natural foods. Then get lucky that you and the bear will be at that spot at the same time. It's not easy and the reason bear hunting isn't easy. Bears in Sept are on a feeding frenzy to fatten up for winter. They'll travel 20-40 miles to find food.

Are you hunting with someone? Do they have bear hunting experience?
