Well here's a simple answer. For many years there was a spring bear hunt, this kept the numbers in check and still left enough bears for the amount of forage food they could find in the "northern" wilderness. As a result of the spring bear hunt cancellation, the numbers of bears have increased but the food source has not. If you're a bear and hungry, you start traveling, unfortunately southwards. Seeing as how you're from Burlington, a little further south, they have not gone that far..yet. Wait until they learn how to use the bus and drop by your place...for a snack or two.
