Dds_hifi; Thanks to you, Trelja, and others for the compliment(s) re my user name. My last name is Garland and in my younger days, ie HS and college, I was sometimes called Gar or Garfish as a nickname.
In an earlier thread on user names I posted that a Gar or Garfish is a fish indigenous to s. central U.S. and is a fast and fierce predator, and also a noble and honorable fish, IMHO. I also agree with Trelja on the name "Swampwalker"-- a fellow Soil Scientist. Cheers. Craig.
