Gather 'round, while I elucidate, everything I've learned over a decade of visiting Sleepy Hollow, New York, during the Halloween season. The only thing you need to know in advance is that the Headless Horseman is my favorite monster.  All of my OTIS articles on Sleepy Hollow. The 2019 OTIS Halloween Season is in full swing over at oddthingsiveseen.com.  Want to learn about the oddities I visit in real time? Follow me on Twitter, Facebook, or Patreon. I also write other books that you can buy. Spooky books.
