Its a photographer's dream to take picture of a perfectly still reflecting lake with a perfect clear sky and fall colors on trees.
Add to it, a horse perfectly position, drinking water and producing the perfect ripple on the still water.
Add to it again -- its a white horse.
All of these happened at Nako Lake, Himachal Pradesh. Its a small, but famous lake (among tourists) in a small village at an altitude of 12,014 feet.
