To find natures big rainbows check for the right conditions. Bright sun to your back and rain clouds off in the distance in the direction of your shadow. If it is later than 4:30 to 4:30 in the afternoon or earlier than 8:30 to 9:00 in the morning and the above conditionsare present, there is a very good likelihood that you'll find a rainbow. If one time you don't see one keep on looking. Knowing when and where to look means you will find a lot more rainbows than most people. Other places you may see rainbows formed are in the mist from garden hoses, lawn sprinklers, in fountains, in the ocean as the waves hit rocks and create a mist, looking down into waterfalls, and in the mist wake created as a powerboat moves through the water. Some less common places are in the spray created as cars drive through puddles and in the moisture mist from the wings of an airplane. The thing to remember whenever a mist or rainfall is around and the sun is out is: you can only see a rainbow if you view the mist with your back to sun.
