"Where are you located?
I think most here in Denver don't bother with green aspen..."

I'm in the Dallas/Ft Worth, Texas area - but my green aspen came from
south of La Veta, CO. That's where I'm building a cabin and harvesting
my neighbor's cut green aspen (HE cut it, not me). I'm also using
standing dead aspen for trim in the cabin. It would be nice to turn,
but not until I've used what I need otherwise. All the SDA cutoffs
will come back to DFW with me for later turning.
