Trenton, Ray's advice is spot on, I've hunted the U.P. twice for bear with a good buddy, we were hunting around Naubinway. I was lucky the first time we went, and he got one the second time we went. I was able to get day old donuts from the local grocery store, I shot sporting clays with the store manager, and he would bring them to me already frozen in a big garbage bag at no charge!!! We also used bacon grease on the logs covering the bait, and on the ground around it, used cooking oil would work also if you could get some from a local restaurant, they'll step in it and get it on their feet and as they walk around leave a scent trail for other bear in the area to follow back to your bait. I also used anise oil mixed with a little water and sprayed it on the trees, to help add some scent, and also tried to cover our scent a bit, vanilla would work also as a cover/attractant. I have also heard of people using the bacon grease to do a burn with a small camp grill, and metal coffee can just to put the scent into the air, we never tried this.
I have also gone to New Brunswick and hunted with an outfitter, and the advice about the bears getting used to the baiters scent is spot on also. My hunt was a 5 day hunt which started on a Monday, we arrived Saturday evening, had breakfast Sunday morning and met the guides, there were 3 hunters per guide, and went with them as they baited. We were only allowed to go as far as the treestands so we knew where they were, and climbed in to make sure everything looked ok, the other 2 hunters waited at the truck. They are allowed to use barrels there, so as they were baiting, they were banging the buckets they used for the bait around and banging the barrel, they would do this as we were going in to hunt also. While we climbed into the stand they would freshen the bait, and it wasn't long after they left that bears would start to show up.
Also, a point on clothing, bug tamer suit or something equivalent, and a thermacell or two. I actually used two while in New Brunswick, I would use 2 when I got in the stand then shut one off after 10-15 minutes and use one up then start the other when I needed it. I also used black nitrile gloves for my hands, they'll make your hands sweat but the mosquitoes, and black flies couldn't get through them. Good luck on your hunt when it gets here and keep us posted as things play out for you!!!
