Virtual Map Pins

  So after Stig returned from Iceland, he thought it would be kind of cool to put up one of those big maps with pins in all the places he had been (he traveled via Panama City and Osaka). Unfortunately, Stig doesn't have any free wall space.
  After we argued for a bit about whether he should take down his ancient Def Leppard poster, we agreed that being able to do this on a computer would save a lot of space. There are plenty of map programs, but are there any that allow you to insert virtual pins?
