Photographing kids

I love taking photos of kids in their element which is one of the reasons why I don't have a studio.  Nothing like a photo of a stiff kid with an forced, awkward smile to convince me even further!
When kids are in an environment that's non-threatening and fun for them they generally forget that you have a lens pointed at them.  This isn't always true about adults, myself included.
I had fun this Memorial Day weekend photographing some children having fun in a backyard.  Even though I shot about 100 photos it never seemed to interfere with their candidness.
