The poster is not exaggerating about the rocks. I grew up in that state and worked on farms as a teen, worked on our own small crop fields too. The sound of a tractor plow grating off yet another massive rock while plowing a field is unforgettable. Horrible, horrible sound.
Don’t those rocks damage farm equipment? And how did people deal with that mess prior to gasoline engines?
Tough, New England farmers were, really tough!
