With Halloween just around the corner, a good team logo to feature is this one, of a minor league baseball team that played in the Pioneer League from 2008 until 2011, the Casper Ghosts. Based in Casper, Wyoming, the team played as the Rockies from 2001 to 2007 before taking on the spooky new name, and along with the name change, introduced new team caps that had a ghost logo that glowed in the dark. Unfortunately the team is moving to Grand Junction, Colorado next season.
