Thinking of late June trip but want to avoid 4th of july crowds? Any idea when they start arriving usually?

It really depends on what day July 4 falls on. This year, it's on a Monday, so the crowds will probably start arriving on Thursday night, filled with all those people who took a long, four-day weekend.
