Well welcome to Massachusetts in May, Rick! As far as I know, there's no official 10th Planet affiliated gyms or hotboxes in MA, but there's plenty of good jiu-jitsu to soak in while you're here. Feel free to come by my school Best Way BJJ located on the south shore and drop in!
Of course, we're a Gi school with only two days dedicated to No Gi (Friday night and Sunday open mat), but the lineage speaks for itself. My instructor was taught by De La Riva through brown belt and earned his black belt directly from Ricardo Liborio. He's still very close friends with both of them, and every year Liborio comes to MA for a seminar, which I think he's also trying to do with DLR. His first visit to teach a seminar for Best Way was this past September.
