Boring technical point here, it's not he air you are paying for but the compressor to pump it up.
Back in the days of old-style service stations they would always have a compressor anyway for the workshop, and it was nothing to run another air line outside. There was no real cost. Nowadays you need a special piece of equipment just to do this.
I always remember seeing a guy at a service station once, he was having a kids party later that day and had brought down 100 balloons to inflate!

There are gas prices websites and speed trap websites. However, is there a free air directory?</font>
Some states, such as mine, require that the air and water thingy be free, at least with a puchase. If not buying anything they they tend to either charge 25 or 50 cents.
A good bicycle pump (the one for home use with the feet pegs) will do the job for free if you supply the labo(u)r.
TSA Clerks: How do you look at yourself in the mirror each morning? How will you explain this to your grandkids?
I notice that the 'bargain' (Speedway) gas stations seem to have free air, while my nearby Mobil station charges. Granted I think they will 'comp' you with a gas purchase, but then I have to go inside and perhaps wait in line.
Help! I've fallen in status and I can't get up.
If you can't spell it, you probably can't afford it.
