IMHO, Major parks continue to price themselves right out of buisness. You can't continue to build 20 million dollar high maintenence rides and keep the addmission price down and not long after you build them, Folks are looking for the next best thing .
A good designed wooden coaster has proven itself time and again as far as keeping them comming back for more.
No Doubt, Thunderhead, Like Beast and other great woodies will have lines as long as they were when new. 20+ years from now.
Rob, It's no secret that i love wood coasters. I believe every park has a place for steel and even a variety of steel. I trully think some of them are Da Bomb as far as first impressions and first several rides. I also see several parks with 2, 3, or even 4 wooden coasters that seem to do every bit as well as THE NEXT BEST THING.
SFGADV can build thier launched top hat and Im happy for them. If they wanted the biggest return on their investment though, They would build a good wooden coaster and maintain it as such.
Thunderhead, has a decnet amount of airtime, but nothing overwhelming. Here is something some might like to ponder on. I'm an airtime whore, But i didn't think that Shivering Timbers or Thunderhead had very good airtime so what type of airtime do I like? :)
