Greener pastures

This is Zoey. She is a Black Lab/Whippet mix. She has the speed of a greyhound and the vertical of a NBA player. On a good day she could easily jump the four foot chain link fence we have...but she doesn't. Now that it has snowed so much this year, she is sitting on about 2 1/2 feet of snow and could easily "walk" over the fence. Today, she looked to be pondering that question..."Is it really greener on the other side?" Or in our case, in Minnesota, in the dead of winter..."Is it whiter on the other side?"
