^That's not true. I can't think of any Shapiro attraction that opened for opening day. They all opened Memorial Day weekend. Even the Bizarro transformations, which was essentially just a paint job and some added theming. Same can be said for X2, which IIRC, didn't open until June. Most of the new Thomas Towns opened in June.
With new management, GCG at SFNE opened with the park, X-Flight opened the weekend after opening, New Texas Giant opened in April, etc etc. I'm not going to get into the argument, but Six Flags finds that opening new attractions later in the Spring is better for attendance. They get people out to the park in the Spring and tease them with the new attraction.
In fact, this corporate policy was actually put into place by Shapiro. Obviously it is working because it makes the guest who came with a general admission ticket upgrade to a season pass so they can return at a later date. Six Flags could open everything up for each parks opening day. They just don't want to. The only people who complain are enthusiasts... If new management found that this strategy didn't work, they would've changed it. Look how many policies were changed under Al Weber and Jim Reid-Anderson.
Anyways, this will SURELY piss you off. Boomerang clearly isn't a priority, which I get.While it may sound like I was defending Six Flags above, a June opening for Boomerang is upsetting. I mentioned how GCG opened with SFNE in 2011, SFStL could've been able to open the small coaster for opening day. Or at least a few weeks after opening like SFGAm and SFOT.
