What's a kangaroo doing in New Hampshire?

In 2008, a kangaroo was captured in Wisconsin. Some years earlier, two cops were slightly injured trying to capture a kangaroo in Chicago. (A version of that sighting made it onto an episode of ER.) Now two skeptics - and I mean Skeptic with a capital S, as they were members of the Granite State Skeptics Society -  describe seeing what they jokingly called a chupacabra but what certainly looked like a kangaroo that hopped across the road in front of their car at night.  The ears were oddly short for a kangaroo, but otherwise it fits and nothing else I - or they - can think of does.  Unless it's a prop left over from a SyFy movie,  someone has lost a big marsupial in a place no big marsupial should be.
