DENVER -- According to a University of Michigan study, kids from 8 to 16 years old only get about five minutes of out door play time per day.
That, according to Great Outdoors Colorado, is not enough.
"They're not getting enough unstructured play time. They are over-screened, over-scheduled and over-protected these days," GOCO executive director Chris Cascilian said.
So what are kids doing with their time?
"They are on their IPhones and tablets, and not getting outside and playing like those of us who grew up here in Colorado used to do back in the good old days," Cascilian said.
A new ad campaign by GOCO focuses on getting kids younger than 12 outside. GOCO has created a list of 100 things to do before you're 12.
Roll down a hill, go on a picnic, build a fort. A real fort, not one on Minecraft.
"It doesn't have to be a lift ticket and a trip to the mountains to get outside and have fun," Cascilian said.
To reach the masses, a five-year, $4 million ad campaign is under way using billboards, TV ads and bus stops.
The challenge will be to get Colorado kids to listen and the best way to reach them is through social media.
