I've found a curious thing about spending time in polar bear country. I'll spend hours in a small willow blind scanning the horizons for polar bears. Just when I know I've spotted one, a quick look through the binoculars will reveal a large shiny....... boulder. Twenty minutes later and the sun reflecting off another boulder looks just like a polar bear.

But, when a polar bear comes into view it is so obvious. Their white hollow fur almost glows and there is nothing quite like it. Then I wonder how I could have ever mistaken a glacial erratic for this magnificent creature.

It is that glow which the background is designed to enhance.
