On one site, I had 2 one- year-old cubs climb up to my tree stand. One kept trying to climb around me; I had to hold him back with my foot and then push him back down.
The other cub ran into the bottom of the tree stand and climbed back down. That is, he climbed back down after the sow, who was right behind him, climbed back down.
Guess you’ll have to take my word that it was kind of exciting there for awhile.
Unfortunately, I didn't have a movie camera and my still camera batteries soon went dead (with my spare batteries back in camp).
