That is an informative post.
I often wonder how trees can survive in a freezing environment in winter, if, as you say, they remain at least as hydrated as in summer. Don't evergreens have a unique ability to live even though their cells "fracture" in the freezing cold. I saw a TV segment on this one time but forget the details... How do hardwoods endure?
And neat use for olive oil, Tim. Must keep the hands in good shape too: good moisturizer. I wonder if car mechanics' hands would be helped by an olive oil pre-treat?
Slippery wrenches maybe aren't the best, however.
