This wasn't just about the two nodes where the road crosses the
boundary of the forest. It was about the whole road in the middle of a
forest. There, everybody just assumes that there will be no trees on
the road. And the same is true for a road on the boundary of a forest,
IMHO.

Who is to tell whether a road next to a forest is logically part of
the forest or where the official boundary of the forest is? 

So, since I don't know better I use the centerline of the road as
boundary for the forest unless the trees start more than a few meters
from the road. If someone has more accurate data than (s)he can map
the real forest boundary.
