Freeman Park will be an absolute Zoo on the 4th! We used to do it every 4th, till around 3 years ago, the crowds just got too big getting on the beach. Maybe it was just a bad day, but I waited several times in line, well over an hour to get out there. Just may want to keep that in mind, if deciding to go there.
Never been to URE, but have to imagine it won't be as crazy.
