I enjoy the challenges of NIBs - my breed of choice is Arabian, though I have a couple of side-projects here and there. My NIB GPs (from 2010! have I really been out of the game so long?) are all now well behind the curve and so I am starting from scratch. It's exciting, but daunting. I can't remember how to play!
I have a nice collection of original foundation Unicowrns from the days they could only be acquired by being fast-fingered on the forums (circa 2008). You can view them under my 'Other Horses' tab.
◦sigηature Arabians' highest current NIB GP is: 414.03.
