Fall in PA will be tougher than spring in BC. BC, you can see 50 bears a day as they are out and about eating new grass like cows and the boar are looking for sows. Plus you have 20 hours of day light. PA you're probably be looking for acorns first, bears second. Fall bear will be more like sneaking up on deer. Difference is bear won't be as jumpy as deer and might give you a bit more time to get close if you mess up your sneak and they figure something isn't right. Deer say forget this and split if they think things ain't right. Bear lots of time want to know what's causing that ruckus before deciding to split.
