Summer is half over. Know why? Because Maine's blueberry harvest is underway.

And blueberry growers are expecting a pretty good crop this year.

University of Maine experts expect an average or slightly above average yield of 80 million to 100 million pounds of berries, thanks to adequate rain in May and June.

Blueberry specialist David Yarborough says the hot, humid, but largely dry first few weeks of July stressed crops to some degree. But he says recent showers are refreshing them.

Love to head out and pick the little blue bubbles of yummy, juicy goodness?

If you are in southern Maine, there are probably a number of pick-your-own stands. Next week the blueberry harvest should begin in the mid-coast area and the first week of August in the extensive blueberry barrens Down East.

DID YOU KNOW: Maine is the nation's top wild blueberry producer? Last year's harvest came in at 3 percent above the 2006 crop.
