Denver's traffic isn't exactly a secret; even the kids have caught on.

Former 9NEWSer Tawny Clary snapped this photo of her son Foster and sent it to Next.

She said "You know Colorado is getting crowded when you go in your backyard and your son says, 'Mom! look at my traffic jam!'"

Foster gets it.

Makes you wonder what Front Range traffic will be like when he's old enough to drive.

Will we have self-driving cars, zooming along safely inches from each other? Or will we just keep widening highways only to fill them with more cars - economists call it induced demand.

OK, we're way off on a nerdy tangent now...
