Even when standing outside in front of your house, walking the dog.
This morning, for instance. I was in front of my house and, well, this incredible spider web just appeared in the tree in front of our yard. Thank goodness I didn't walk into it!
Normally, it would be difficult to see. I got lucky as the sun was hitting it just so -- from the top left of the frame. A few seconds later, I lost the light and it was gone. (the sun beam, not the spider!).
Sometimes even the most mundane places can once in a while show you something incredible.
Have your camera ready.
