Haunted locations in western Michigan

We're writers of a Michigan paranormal book series. We're looking to find and investigate locations on Michigan's west coast with suspected paranormal activity. We're particularly interested in hotels, B&B's restaurants, or historic sites. Any suggestions (besides the Traverse City asylum or Traverse Cty playhouse)? You can post here or email us privately at: haunted@mivg.com (website: www.hauntedtravelsMI.com)
