Police said the boy grabbed the keys to his grandmother's car, moved his booster seat from the back into the driver's seat, started the engine and put the car in reverse.
He wanted to go to Appleby's.
After 49 feet, he struck a curb, then went nearly another 30 feet before hitting the electrical box. Shaken, the boy ran back into the townhome complex and told his grandmother about what he did.
By the time both the boy and woman went back outside to the scene, police officers were there, responding to a call of a hit-and-run.
Officers questioned the boy and the 6-year-old fessed up in a manner that was very matter-of fact and yet very adorable, said Broomfield police spokeswoman Colleen O'Connell.The power outage affected about 200 people.
