A Utah man and his son are million dollar winners in the Idaho Powerball lottery.

Mike Middlemiss, of West Valley...and son, Chris, of South Jordan...have been buying lottery tickets together -- north of the border -- for years.

But this is their first big winner.

They say the lucky ticket was purchased on Chris' birthday, last month.

He plans to pay off student loans, while Dad will use the cash to move his retirement date up.
