Crowd level predictions are all over the place -- none of the crowd-prediction websites agree; seeing everything from 5/10 to 10/10 DO NOT GO. Anyone been there over the actual 4th who can report back on what the crowd is like? Will it make much difference that the 4th is a Wednesday, not a "shoulder"/long-weekend day?
