Snowball is a giant cat head in the Arts District created by foam sculptor Jesse Smigel. Before the #snowballselfie becomes a big First Friday trend, there needs to be a warning: watch for traffic. In order to take a Snowball selfie, the person taking the photo will most likely have to stand in the street. It's dangerous. The #snowballselfie is also a #riskyselfie. Caution your children. Besides that, #snowballinvegas is a cat and not a dog, so, 5 stars.
