I went bear hunting about a dozen years ago only to have a bear charge us during the baiting process.....
I sat in my stand in the morning not seeing anything, the guide we were with was going to replenish the bait barrels during lunch hour. Me and another guy (that was up there to take pictures for his brother) offered to go give the guide a hand baiting. As we get to the first bait site, he lets me take the lead just incase a bear is at the bait barrel..... As we round the last corner, bait barrel is knocked over but not bear. We replenish the barrel with corn, grain feed and a bucket of malaises...... We leave and start heading over to the next barrel
As we get closer to the bait site it starts raining and begins raining really hard. One of those downpours that the water is just pouring just pouring off the lip of my hat making visibility tough. Guide tells me to leave my newish shotgun in the truck and take along his old shotgun. I agree, (turns out not to be the smartest move)...
Again as we near the bait site, I take the lead, again barrel is knocked down but no bear....
So I walked in with his shotgun, the other fellow carried the bucket of molasses and the guide the grain, corn sack feed....
As they prepare to refill the barrel I take a walk around and notice a lot and I mean a lot of bear poo and remember thinking wow, lots of bears here....
I turn to see the guide having trouble with the feed sack, I decide to help him out.... I think about putting the shotgun down but thought oh ya, as soon as I do that a bear will come in and eat us and I will be the jackass that put the shotgun down.....
So decide to keep the shotgun shouldered and pull my knife out to cut the feed sack. Now this is where it got interesting.......
As I am making a cut in the feed sack I notice the guy that carried in the molasses make a weird frightening motion, I turn back to where he is looking (behind me) and see this big bear tearing in toward us...... I turn with shotgun in hand and take two of the fastest shotgun shots of my life, less than 20ft from us (missed both shots but what a rush) The bear turns at the first shot and keeps running away from us at the second one..... We all just gasp and are in WTF just happened mode......
The funny or weird thing was that when the bear was charging in on us, all I heard the guide scream, shoot him Frank, Shoot him.... you know what raced through my mind when he was screaming that....... it was shut up you are going to scare him.... Man that was a strange thought back then but true

Not sure how I missed him so close but I did, what a rush....
The best we can figure is with the rain coming down so hard, that the bear never heard us on the way in but after those fellows kicked the barrel to unstick the old feed from the side of the barrel, that big bear must have thought there was some competition (other bears) in the area, only when the bear heard the guide scream out that he realized it was humans on the bait not other bears...
I cant remember if I shot my bear that weekend but do know, two smaller bears where shot off this bait on back to back nights.....So big bear must have been bedded down and thought those smaller bear where eating his food....
That has got to be the most exciting and one of the most coolest adventures (hunt) I have been part of, something I will never forget.
