Fascinating. Now I am wondering about sapwood vs. heartwood where the limbs intersect with the trunk. In a tree, the sap travels through the outer sapwood, and the heartwood is dead, but what path does the sap follow to get to the limbs? There appears to be no capillary connection between the sapwood of the trunk and the limbs. Is the pith (the center) of the tree also a carrier of sap? Is the pith alive, and the heartwood dead, and the sapwood alive?
Incidentally, the sapwood carries a decay resistant compound, which is why this post has rotted away in this pattern. The living part of the tree (when it was cut down) hasn't rotted away, and the dead part has. I guess I answered my own question. |

yeah, it's not a *law*, more of a guideline, really.

A young teen standing in the backseat of his Dad's convertible near the finish line snapped the only picture of the Snake during this incident with the last picture on his roll of film.

Man, that looks like one of my exit/on ramps.
I guess it looks like a lot of exit/on ramps.

Yeah, if they don't put in a cloverleaf, this is the alternative.

It fooled me, I had to make sure it wasn't the ramp I used for 28 years.

The good thing about getting old is that it don't last long.
That ride will get ya to the end quicker if nothing else...
