As much as this forum seems like the last bastion of a sane, reasonable, non-robotized, non-commericalized internet (THANK YOU SITE ADMINS and CT community!), I still never use my real name on forums.
So, being born and raised in the northeast and an ecologist, I cast about for tree names. On other forums, Quercus is often taken, and Acer might leads folks to believe I like laptops. Tsuga was the third tree that came to mind.
8 because it's a nice round number, lucky for some, easily factored for others... I like that if you tip it over it turns into infinity.
