How many current steel coasters will still be running in 40 years?
Perhaps that should be a part of the overall calculation for cost
effectiveness. In other words, even if it cost more to maintain a
wooden coaster annually, does that necessarily mean that over a 50
year period the wooden coaster cost more...especially if the steel
coaster was more expensive to build in the beginning and you have to
replace it with something else 40 years down the road?
That is the type of question some people choose to ask about Hybrid
cars right? If they cost more on the lot...how long does it take to
"catch up" in terms of savings to what you would have saved buying the
non-hybrid to begin with and then what if you have to replace the
inverter 10-15 years down the road on the hybrid? Annual cost may not
be the only factor to determine what is best"cheapest" for the park
