Anyway-good luck as you head toward Katrina country.Richard***--> the email reply from my dad, via my mom (my mom uses email, my dad doesn't.) my dad has worked in the timber/logging/sawmill industry for at least 25 years....An answer from Daddy re:trees, or as much as I can remember: Trees are planted in rows like that, because they are farms and the trees are a crop, it is not a forest.
