hey, this is random...but, i saw ur comment asking y cass needed an ambulance for a sprained ankle.... They weren't sure if it was sprained or broken because after she fell she couldn't put any weight what so ever on it... But, the reason for the ambulance was because they didn't have a car to get to the hospital, which is why they used the ambulance... They didn't call it though, the ambulance was already there... Some venue's require an ambulance be stationed nearby for crowds above a certain size
