Why are the Bears So Hungry?

This morning, I enjoyed a great time with some bright young women, trying to teach me some more about this amazing world of blogging. I learned a few new things, but just forgot one of the basics: always SAVE your composition before you start previewing it or anything else, so, now I am having to write this all over again.
I was telling Nancy Simpson about the bear visitation here in Wesley Mountain Retirement Village, where I live. She told me about one causing a stir in Andrews, too. Now, tonight, I received an email from Nancy telling me that a young bear came right up onto her patio, which is off her dining room. Nancy said bears have been on her property before, but never come right up to her house before. All these incidents invariably involve bears tring to rob bird feeders. My next door neighbor saw the bear crossing the road in front of his house, and there in the road was his bird feeder, or the top of it, at least. The pole was bent over in his front yard.
Have we had a bumper crop of young bears this year? Or, are they just hungrier? It's still too early for the blueberries and blackberries to be ripe, so I suppose the deep woods' wild berries are not ready either. Anyone else know why the bears are so hungry and bold this year?
