The easiest way to get a bear would be to go to a state like Maine and use a guide to hunt over bait.
Canada as well. However, this requires long hours on the stand and some people don't want to hunt over bait.
These hunts are on the cheaper side of guided hunts though and most people could save up enough money to get the best opportunity at a bear.
I haven't done one yet, but I've been considering taking my bow one of these years and doing it. As I don't see myself ever having an archery opportunity at a bear on my own.
Maybe by luck in PA. but it would be unlikely.
