A season may not educate anything. But ongoing pressure will as moms educate their young over time. A number of seasons will educate bears provided their numbers support that--but that taking place appears extremely unlikely.
Government stepped in and put up a fence. Expect more of the same, a precedent is set. The expansion of the urban population mindset in Montana will only encourage it as a bad bear will become a celebrity.
During the recent wolf expansion in the UP, the greater numbers of wolves led to pack education, as boldness (like eating pet dogs on a chain in the yard) eventually ends up pissing off involved people who take matters into their own hands---regardless of what the newspaper editors in Detroit furiously wrote.
Grizzlies don't run in packs, Montana doesn't have a bridge and it sure is a lot harder to dig a hole on a big rock unnoticed.
