section).

the NSF, in the mts in Oregon.  The forests around Fort Lewis in 
Washington State  - again, undisturbed - have good diversity, but be 
careful of the tanks rolling around.  They get fairly nasty about 
unauthorized people on the property, so maybe not a good place to go 
on your own.  And again, you have to know where the place has not 
been disturbed.

they are good or bad guys.  You need a DIC microscope to do that.  
Send them to SFI for ID.  Or hope for the best in your compost.
