I chose the name White Oak because it's a favorite tree of mine. In fact, I have a ceramic coaster with an image of a white oak. There are also white oaks in front of my workplace.
I don't have any white oaks on my property, but I do have some pin oaks and willow oaks (another favorite).
The 2006 suffix is because WhiteOak was already taken, so I added a reference point for when this user name was created.
