The concept was born at BrickWorld 2010. Kelso and I were talking and we thought "hey, wouldn't it be fun to do a collaborative?" Sure it would. So after a little thought (and some other concepts that will remain nameless as they may be future projects) I said to him "Hey, I got it... let's do Lord of the Rings." He says to me "You mean like... a few of us build Minas Tirith or Barad Dur?" "No, no, no..." I replied "Let's do Middle Earth... ALL of it."
