Dear Sterling, Robert, List;
All I know is I sell a heck of a lot of petrified tropical hardwood and
palm wood that was frozen here in time in Wyoming. And I sell a lot of
tropical hardwood and palm that was petrified and then ended up in a few
(five is the last count) glaciations....
My opinion; weather, seasons, and list topics are cyclic, enjoy the ride.
Best,
Dave F.
