Space on my phone is a precious and limited resource, so most videos are deleted as soon as I've downloaded them to my computer. But two are off limits. And they'll remain so as long as I have the device. The videos show two of my daughters, then ages 3 and 2, bravely stretching out their hands to feed carrots to Kimba, one of the African elephants at Cheyenne Mountain Zoo, and then skipping back to my wife and me for hugs in delirious excitement. They couldn't believe how lucky they were to actually touch an elephant.
