B2 -- In Colorado sows with cubs generally den earliest, starting mid-Oct. Big boars den last, mid-Nov. Combine this starvation summer with current rifle seasons and gutpiles everywhere, and you should have plenty of bears to spot and stalk. That's what I'd do, and perfectly legal and ethical: go to areas with lots of hunters and gutpiles and some open visibility. Glass until you see a bear, and stalk it. Or, if you find a gutpile in the woods a bear is visiting, take a stand nearby. Bears don't always find every pile, and it can take them several days. Watch for magpies and ravens. Dave
