Ol Mike, I see your point. I've had 3 occasions where the bear showed interest without aggression. The tent in Montana being one.
The 2nd was the hiking trip at Dogshead Creek. In that one my hiking companion was wearing perfume. A huge NO-NO in grizz country!
We spotted the bear at 50 yds. up a double track. We yelled, waved our arms, etc... He kept coming. So she hid her face in my neck. He walked up to about 6', stood up on his hind legs and gave us a look over. Dropped down, sniffed her wrist right were she sprayed the perfume, walked in front of me, rubbing against my legs with his shoulder, walked about 5 yds. to my right, gave me a cautious dog look, walked back, rubbed against the back of my legs and walked off. He stopped to pee on a bush about 10 yds. behind us. I never felt threatened. I was unarmed and had no bear spray with us. I just had to stand there and deal with her so she didn't freak out. That was more stressful than the bear.
The 3rd. was just about a 2 months ago. I was portering just north of South Leigh Creek. I was at the junction of the Green Mtn. Lakes and Tin Cup Creek trails. There was a grizz across a meadow about 120 yds. My wolfdog sniffed him out but seemed to pay him no mind. I yelled to let him know we were there (they're nearsighted). We kept hiking. Then he just charged. He crossed the meadow in about 8 sec. He stopped about 20 ft. away. Put on a big show, posturing, etc.. Then walked off. He paced us across the meadow at treeline. The trail ducks into some tight woods and switchbacks down. I could hear him above us. When we got into the densest area he charged again. He flowed over all this deadfall like it wasn't even there. AMAZING! He stopped about 8 ft. away this time. I had my bear spray in one hand and my trekking pole in the other (aimed straight at his eyeball). He fluttered his lips and flared his nostrils. But that was it. He followed us down to a bench above the parking area. When I reported it the biologist told me the bear was exhibiting "hooligan behavior". Like a teenage boy acting tough. She said bears do that to each other to test limits.
I never felt in danger in any of those situations. I wasn't!
