yup, bears love burgers and dogs...ummmm ummmm good. I think park rangers say that the noise and smell of people is enough to discourage the bears during the day. They come out to get the tasty stuff they smelled after the people go to sleep, which is why your supposed to put all that stuff away, really, really away-- cause they give up quick and move on if they can't find what they are looking for. Less contact with bears is always better than more.
