Forgot to post this the other day, but Knott's has officially released Hangtime's opening date... May 18th.
While it's a far cry from the original speculated date of March 31st, opening day is just a little over a month away. Instead of rushing the opening, they are taking their time with finishing off the station and queue areas, as well as getting the light programming down.
In my mind, it's better to open the ride when it's ready, as the media is going to be taking a boatload of pictures. There is also the chance of a soft opening a week or so beforehand.
