there is a tech that walks with the dragon thats has to push a button every time it fires. if for some reason they see it unfit to fire (wind, trees, preformers to close) they will not push the button and it will not fire.
there's a multitude of reasons: weather, they need to close the space between floats, audio issues, they also walk and wave coming out and going in the gates at step off/down... that's just a few the come right to mind.
this wasnt yesterday, however this is the weather contingency. you can see in the beginning of the video that it had rained earlier, and possibly more to come
actually it was due to weather that everyone stopped dancing. they had to get the parade out of the park, so they stopped dancing so the floats could go faster.
she was but I she had to leave.... just bc something wasn't there when the parade got to you doesn't mean it didn't go out. there are many factors on why a performer may leave. so you cant say she wasn't there, she just wasn't there when YOU saw it
parade steps off at 3... no earlier and hope to god no later... you have to be mindful of the things that go on backstage as well, its not like CM's live there and they tell to go at a moments notice
