Meet the diehard tennis fans camped out in Wimbledon's epic "queue"

London — Tennis fans around the world started tuning in Monday to watch the iconic Wimbledon tennis tournament as it got underway in the leafy southern corner of London where it's taken place since 1877. Millions of people will watch two weeks of grass court action on their screens — but far fewer will actually get to take in the sights and sounds in person, and being one of them is no small feat.

Wimbledon tickets are available online, but you have to register by a certain date and there are still no guarantees.  

"They get snapped up so quickly," tennis fan Wendy Bartle told CBS News as she headed for the hallowed ground of the All England Lawn Tennis and Croquet Club, or Wimbledon, as it's better known.
