@RocketGuy I have to guess (I am guessing, not declaring) that if those bear intruder pics are valid, they are in areas where bears are starving and/or careless people have been feeding them.
As a kid I would summer in the Colorado mountains. I saw bears a couple of times in the neighborhood. And yet my aunt & uncle would let us kids go “camping” by hiking up from the house with blankets and pillows. We slept under the stars. We kept a fire or kerosene lamps going. We didn’t eat outside.
I also hiked around the mountains above Los Angeles a lot in the early 2000s. There were no dire warnings of bear attacks. Here are the Angeles National Forest’s Be Bear Aware guidelines
Bear sightings and activity seems to be increasing this year. Be aware of bears and follow these safety recommendations.
Keep a clean campsite. Store food and garbage out of sight and in closed vehicles.
Never put food scraps or litter in the campfire; it attracts bears and skunks.
Don’t keep food, medicine, chap stick, shampoo – Anything that smells – in tents or sleeping areas
Store stoves, barbeques, and dutch ovens in a vehicle or secure place when not using. Do not pour used cooking oil or food remnants on the ground.
When camping in the back country hang food and garbage from a tree limb, at least 10 feet from the ground and 5 feet from the tree trunk. This tree should be at least 100 yards from your sleeping area.
Some bears also target motor oil, insect repellant, liquor and other things that look like food. Make sure you put these items away.
Remember: Never feed a bear. A fed bear is a dead bear.
