RideMan,
If I remember correctly, the Frontier Lift was gone the season before Iron Dragon was constructed. That is to say, we had one year at the Point with the old Western Cruise still operating but the Frontier Lift gone.
I remember opening day that year clearly, because I was in the Season Pass Center getting my pass, and I looked at the park map and said, "Hey--where's the Frontier Lift?" The reason the attendant gave at the time was that it had been taken down due to wind: "That ride was always down due to wind conditions." I'm sure that's what she thought at the time.
The next year, they broke my heart, as the Western Cruise was gone and the Tin Lizard was in its place. And thus began the decline of the lagoons.
Again, all for progress, I suppose.
