Have you ever heard of “The Great Smoothie Challenge”? This was a term that I had never heard of before my son Wyatt (10) asked me “Dad, can we do the Smoothie Challenge someday”. He explained the basic rules and I responded “Sure, sure – we’ll do that someday…” That was my way of putting him off and hoping that he would forget about it and move on to some other crazy idea. Not likely if you have ever met Wyatt Millar.
