Pokemon GO Halloween Event is live!

The Pokemon GO Halloween event is......Go! Seeing more ghost-types? You should be!  Niantic have started an event, which is giving out more candy on captures, shorter walk times for your buddy Pokemon and more frequent sightings of a few Pokemon, to tie in with "spooky" goings on at Halloween. I've seen lots of Gastly and Haunter, plus Cubone, Marowak, Drowzee and Meowth no matter where I am.  A capture has been getting me 6x candy, too.  So I might actually get some evolutions done this week, for a change. Anyone seen anything else? Looks like Reddit has a good thread going.
