Sounds like you guys need to work on your bear hunting skills.
Hunting bears in PA and out west are apples to oranges. Our success percentages range from 2%-3%, and most of those are camps that put on drives with 25 guys.
Our bear season is short and late in the year. Around Thanksgiving. There is no bait, there are no hounds. The bears live in the thickest imaginable cover.
Sure, you could try calling them. You would have to use mouth calls because electronic callers would not be allowed.
We don't have spot and stalk. There is not vast openings. You have laurel tangles you can't even see into. If you have a ton of private land, you could try calling a bear in. But, you're probably somewhere that other hunters are pushing so the bear will be spooked from the get-go.
