I really wish I could of gone to this event. I've always been a fan of trains, especially steam engines, and have always had a special place for Kings Island & Miami Valley Railroad. Mainly for the fact that it's one of the few, true, steam trains operating in an amusement park today. Like Avatar, I've been riding this train since I was a little kid, not nearly as long though, and have loved it ever since. Also, many people like riding The Beast and now Diamondback at night at Kings Island, but I would encourage you to take a night ride on the train. It's a truly amazing and a much different ride than in the daytime.
These pictures and videos are really amazing to me. I especially like the last one of the train coming into the Losantiville station with the steam just rolling everywhere.
Very nice and very informative TR Avatar. Thanks!
EDIT: Here's two videos I took of the train ride from Losantiville to Boomerang Bay and Back. I know its shaky and not the best quality, but try to enjoy it anyways, thanks.
