Ugh, this is unfortunate. But the important thing is, nobody was injured.
Just a guess, but I wonder if they're going to move the remainder of the slide pieces over soon? The park hours change again on 6/18, to where WnW will be open until 9:00 PM - peak season. Usually around that time TM parking changes occur - in the past, they have used the current VB slide storage area for guest & TM parking during that time.
