Re: Mowiol for gum

Just dropped into this thread, but...
As a native Arizonan,
I believe I read long ago that mesquite gum was acceptable (and 
used to be collected), and several species of acacia thrive in 
Arizona. We were familiar with gobs of sap hanging below damaged 
or stressed limbs. Maybe somebody who still lives there could make 
a few bucks.
