I got a big hug and a look of amazement from a blonde-haired 8 year old girl saying "I love my new gun", and an almost 2 year old little boy running wide-eyed yelling "Sana Caus bring toys, Sana Caus bring toys!", and a hug and a kiss from my beautiful redheaded wife who said it was "The best Christmas she'd ever had".
I wouldn't trade those memories for every new tractor and implement in the world.
