My city has a very cute baby carriage and tricycle parade around the Common (Melrose not Boston) on the 4th followed by a free concert at one of the local outdoor venues. We have our own symphony, the MSO, and they typically perform a few times each year.
In nearby Boston, where it all began - sorry Philly, there will be harbor fireworks on the 2nd for Harborfest, and then the traditional Boston pops and fireworks on the Esplanade on the 4th. It’s going to be hot and humid all week. Not sure if I’m going through with my plans to meet friends to photograph the harbor fireworks. This is not my preferred weather. I usually skip the Esplanade on the 4th as I’ve been many times when I was younger and it’s great but is a lot of work to get in/find a viewing spot/wait for hours/get out.
