mmmm. have to find that website again. I forget which states, but some states it's actually a law that gas stations must provide free air and water for residents of that states. Under the law, they can still have a pay machine, but must provide residents free use. I know CA is one of those.. Just take your cheap ass to Advance Auto, Autozone, or Wally World and purchase a cheapy inflater/compressor. I keep one in both cars, a jump start/compressor combo in the garage, and 2 compressors for air tolls in garage as well. The car ones are <$20.
