By far the best attractant I have used is Big Bear Scents they are a relatively new company but there products are outstanding. I used the bacon sprays and got my pope and young bear the second evening of my hunt in the 2007 mn bear season. I'm not sure if you can get there stuff in stores but i ordered mine of their site...

As for scents everyones right different scents everytime is better for bringing all the bears in the vecinity into the baitsite. I used to stick to mostly meat scraps but have been learning new tricks every year. But nothing beat last year I seen more bears in the first half hour, then I have seen in weeks some years.
I now start my baits with fish and meat scraps then closer to august move to sweets and a mixture of corn, honey,syrup but always use grease throughout the year becuase it is true about loading all around the bait with grease and all the blacks carry it home now they have a roadmap back to you and all the other bears in the forest around your treestand can also follow the road.
As for the 270 argument common guys you all know a 270 is more then enough punch with the hunter doing his job.
But as you all know if you know me, I suggest the 30 cals, you can't go wrong with a 30 odd.
Here in Idaho baiting is a blast in the spring. I don't fall bait much as I am usually chasing Elk. Anyhow 2 things.
1. Moccasin Joe makes a cover scent called "Apple Scent" Buy about 4 of them and spray them around your bait site. It makes your bait site smell like an apple orchard and I have had bears run into my bait the night I spray that stuff.
2. If you hit your spot a .270 is plenty of rifle for even the biggest of Bears. No doubt about it. The bigger guns are great for bone breakage, but a .270 will let the air out of their lungs just as fast. As a side note I bowhunt and the only way to deflate lungs is with a sharp broadhead....LOL.
Let me start by telling you the story of two Johns.
John number one went on a day hike with a couple of friends in the Cascade Mountains about an hour from Seattle. He somehow got separated from his buddies and became lost. John was dressed in casual cloths for a warm weather day hike and had nothing but a lunch with him. He spent three days in those mountains and luckily made it out to tell the story.
John number two, a friend of John number one, was much better prepared when...
