Hi everyone. Just wanting to ask for an opinion. I am in new York Friday and Saturday and wanting to go to six flags. Friday's forecast doesn't look the best but will the main rides be open in the middle of showers and it's meant to be dry after 2 so will they open at all. Or would Saturday be better but I think this might be busier then. Is it better chancing the weather and hoping rides are open or on Saturday but potentially get on less rides due to queues
