RE: Alternative Bear hunting tactics.
Bacon and honey burns do work well, and are used often to activate the bait site. I use rock chucks that have been cooking so to speak in the hot sun..
Bears are also addicted to the additive in propane. I have taken unlit torches and craked the valve open to slowly let the fumes out. This will bring them in too.
I am not sure if these would be considered baiting in your state since you are not leaving out a bait per say. Direct answers would have to come from your Fish and Game department. If not, you will be limited to locating the food sources and either finding them using the food source and stalking them, or you can sit a well used area and hope that one shows up. if you are hunting in the spring, the bigger boars will be out and about around the late may early june time if your breeding season coincides with ours.
