Raddogz......check this place out. According to their site, they do refills but will take 2-3 days. I'm not sure how up to date the info is on the site but worth checking out if you don't want to make the trip down to carbonicservices.Raddogz said:County of SF does not allow for fill stations and only allows for swap outs at least that's what I was told.
Sucks for me cuz I have shiny tanks
