They ever cancel a Derby???

[wac]

Damn, the more i look at the weather the more depressing it becomes but now there is word that it may actually be really bad on Sat. Has a Derby ever been cancelled due to weather? i know that if its lighting out they will call almost all sporting events but what about this? Sorry if its a stupid question but i was just wondering b/c the thought of the whole day and the great card being run in a friggin monsoon is very depressing.
