“Are you here for the Winery Tour?” This is a Western Grey Kangaroo caught lounging in the wineries of the Adelaide Hills in South Australia. This past Autumn has been a spectacular time for wildlife viewing and I got lucky to spot this guy while mountain biking in the hills. Such a funny stance it just begs the question... Have you been drinking? ...and or... Are you here for the Winery Tour? Such a spontaneous moment I figured it would be perfect for an entry. I hope you like it! Cheers. Photo location: Adelaide Hills, South Australia, Australia. (Photo and caption by Greg Snell/National Geographic Photo Contest)

“Photo mechanic” and photographer Ionut Caras creates surreal concepts by combining the everyday with the unthinkable. His use of light and tone takes the viewer into a bizarre and beautiful world only seen in storybooks and our dreams. Photo: “The observer”. (Photo by Ionut Caras)
