Being from the northeast, I sometimes forget that people in some parts of this country actually cut and burn pine.
My stoves traditionally eat only oak and hickory, although they've been seeing an awful lot of ash since the Emerald Ash Borer made it out here the last several years.
Pine and all other connifers get left to rot where it falls, or pushed into the burn pit. If I lived in a place where oak, hickory, and ash weren't plentiful, then I'm sure I'd burn it. But around here we always have enough hardwoods dying or on the ground, that it's just not worth wasting wood shed space on connifers.
