Wow– do you have pine barrens in Maine? NJ pine barren are the area's with commercial blue berry farms, and NJ is second to Maine for blue berry production.

No pine barrens in Maine that I am aware of but it is a huge state and I have seen mostly the southern seacoast of Maine which is over the border from the New Hampshire seacoast which is where I live!
In New Hampshire we have bush blueberries and some large-farm farmers grow lots and you can go "pick-your-own" or get baskets at the local Farmer's Market or get tasteless big fat blueberries at the supermarket. The flavor of the berries, I've noticed, is affected by what the bushes grow near. Blueberry bushes near pine trees are ok, but blueberries grown near apple trees....they're for me. Sweet! Yum! Now, if you want to talk cranberries, those I know a bit about! wow
