Sounds like some things could be stirring at Frontier City. People have reported markers around the back of the park, though the park says they are just for general surveying, and the go-kart track has been boarded up again.
The go-kart track is a perfect place for a new ride, and as I said before, I can certainly see the new management wanting to put in a new ride for next year to keep their momentum going. The go kart area is the perfect size for a splash battle, or really any kind of big flat. I could see a Frisbee or top scan style ride doing wonders for the park as well. Of course, a new coaster would be the best, and if the markers mean anything, they apparently extend all the way from the go karts to the other side of the Wildcat...
And again, I'm still hearing lots of good news about the park's crowd levels this year. Lots of people have actually been complaining about lines! Seems like the Halloween season has been crazy good for them, save for one weekend that they were rained out and shut down early.
