I've kind of gotten back into the lure and scent testing mood lately. One oil I've found that the bears love is Anise oil. Anise oil has a very strong black licorice odor. I put the oil in a scent egg. This is a round wooden ball with the center drilled out and a short stake attached to it so you can anchor it into the ground. Every bear that came by the camera stopped at the scent egg to check it out.
