UBER and RTD say a partnership they formed this year is starting to click. Since May, you've been able to buy RTD tickets through the UBER app. More than 1,200 tickets have been sold so far. UBER's David Wright says that may not sound like much, but ticket sales have been growing at 42-percent per week. He says that means more people are taking UBER to and from RTD's commuter trains and light rail every week. The UBER-RTD partnership is the first of its kind and is now being copied in Boston and London.
