Well I was sort of banking on it being less than your standard weekday morning rush hour in general, due to the holiday. So if the parade just bumps it back up to that...it's good to know but not good? Glad to know it won't be worse.
I was debating where to come from. Bringing a friend from Pomona, so we could either leave from there and go west (which I assume is worse since it means passing Pasadena), or they come to Irvine and we go together north.
Either way, one of us would go to the other tonight to crash, and then drive straight to the park tomorrow morning.
