I love hunting bear & have been for 30 plus yrs. We (Sally & I) disperse camp always in bear country. What I found IMO is depending were about in the country, black bears are attracted to many things that campers do irresponsibly. I found with my experience is people aka campers do not consider what brings bears to your camp site....food, garbage as of storage & disposal of trash & uneaten food, pets is another & their waste. Bears are meat eaters as of veggie eaters. Another attractant to bears is undone (unwashed) dishes left out during the night, as well as dirty dish water dumped too close to camp. Trash should be triple bagged no matter what & each bag tied off tight. Food should be stored in air tight containers or storage trunks. This storage container should be a expensive food storage locker & shouldn't be cheaped on when purchased.
Bears are naturally afraid of humans, but may become accustom to people by their lack of bear knowledge, stupidity & their poor camping behaviors. This is why some bears will become nuisance animals & will have to be relocated or even dispatched. IMO "I" feel too many unseasoned, amateur campers cause the problem for other campers who like to camp in good bear country by what I mention. These same types have the attitude "I" know it all mentality when in reality they know nothing & are the ones who cause the bears to become problematic.
