I only live 45 minutes away from Carey, Ohio (or 20 minutes from my campus). Carey does not have a pier or casino. Carey is completely landlocked and the only bodies of water are the reservoirs. http://maps.google.com/maps?q=carey+ohio&oe=utf-8&rls=org.mozilla:en-US:official&client=firefox-a&um=1&ie=UTF-8&sa=N&hl=en&tab=wl

Also, there are no old casinos. Most of the gambling that happened in Ohio was either up in Lake Erie or on the Ohio River, closer to the Canada or Kentucky sides respectively, usually through riverboats. The only real interesting thing in Carey is that there is a Basilica and Shrine of Our Lady of Consultation. If you go into the basement, you can see hundreds of crutches, cots, and pictures of people who have been cured at the spot.
As awesome as it was to have Bloody Mary associated with something close to home in 2008 and that Spawning from 2009 was set here as well, I do not think we will see Carey make an appearance this year. Then again, if it is about an illegal/hidden casino (if it is a casino) it could be set here. Still, in my personal opinion, I would rule out Carey.
