A lot of folks in the east think that way and generally speaking, the eastern pines aren't great firewood. Here in the west though, I've found Lodgepole to not be too bad at all. Not top of the line certainly, but better than red maple. About like ash maybe.My dad burned wood for over 30 years, and from my childhood, it was FORBIDDEN to put ANY KIND of pine in that wood stove! I'd have got beaten!
Side note: There is quite a large contingent of eastern firewood burners who think that anything with needles is a pine. That confuses the issue further.
