Interesting. If you go back through KI's tweets, on Jan 28 you will find one seemingly randomly directed at a user that simply states "308".
Link. Looks like the user it's directed at either didn't tweet a question or deleted it.
The tweet that immediately preceded this one was "@KingsIslandPR: @CoasterGeek900 Sometimes late summer, sometimes winter like Dinosaurs Alive!, and sometimes like WindSeeker not at all." in response to this: "@CoasterGeek900: @KingsIslandPR If anything new is coming for 2014, when will we see teasers and signs for it?"
Once again, interesting. Although, it appears they posted a dinosaur teaser on March 8...
