Mammoth, RIFG, and Sticky Fish at the same spot? No drive to providence? Happy and stoned. Never shopping anywhere else. Chris, Liam and team are amazing! The community deserves a spot this good. Foster, Gloster, Putnam, Sterling, nowhere close even close.
Smoking indoors? The right air purifier eliminates smoke and odor in minutes.
