Boston REI Assocation - Which one???

[Max K.]

I'm looking to get involved in the REI community in the Boston area, and it has come to my attention that there are two popular REI associations; one of which is part of the National REIA, and the other of which is not. There also seems to be a lot of bad blood between them.

I'm hoping local investors can comment on their experiences with one or both, what led them in which direction, etc. 

Let me know what you think please. I want to make the right choice!
