I had a close call with a black bear in the Ocala Forest in Florida last October. It was my first time back-packing and I made a lot of stupid mistakes. I had forgotten to bring a rope to put food in a tree. I had the wrappers from some fruit chewies (very aromatic) inside three plastic bags - thinking that would be good enough. Shortly after dark I could hear a bear approaching my tent - going right for the spot where that wrapper was. I can’t say for sure how big it was, but definitely heavier than any human from the sound of the crunching through the underbrush. I banged together a insect repeallant can and an empty plastic water bottle. It finally backed off. I was up all night long periodically banging those things every time I heard the bear approach. I hate to think what would have happened if I feel asleep. I still don’t know if there’s something else I should have done. (Other than go back in time and not make the food mistake). Nothing I found in my research has told me what to do if a bear comes after you in a tent.
