Any Indie Hackers in Boston?

Hey everyone! A friend and I are going to be visiting Boston for a few days at the end of March (the 23rd to the 26th), so I wanted to see if I could get any recommendations on cool cheap/free things to do while I'm there. I also don't have a very large community of Indiehacker type people where I'm from so I would love to meet up with a few people to talk shop and riff on some ideas if anyone would be down for that as well while I'm up there! My friend will be at a concert for some of the trip so I'll have plenty of time to explore the city haha
