hey dude theres a place right down the street from me they r called Pezzi and i always drive by and they have a HUGE sign on the main window that says NITROS sold here, they are located in chelsea mass on washington ave.
Thanks guys, I got it filled at "The Driver's Seat" on Waterman Avenue in East Providence. I had to goto Post Road in Warwick to pay, then they sent me to East Providence for the fill up. $6.99 a pound plus tax. Kinda sucks, but worth it now. I'll see you at the track!
