State by state database of where active members fill their HPA tanks.

I would love to see if somehow we could dedicate a page to SCBA refill stations, state by state town by town. It seems to be very difficult to locate these places. It took me hours of research and I ended up getting a nitrogen cylinder which was a pain because of the restrictions. I think new PCP owners would find this information invaluable. Just a thought that definitely needs some fine tuning.
 
San Diego, CA 92123. Sport Chalet Mission Valley. PCP Gun friendly. Facilities to fill 4,500 psi cf tanks. $5 a fill or you can buy an air card for $45, good for 10 fills. 

If you have an air gun that requires a 2000 psi or even 3000 psi fill then you could buy a 3000 psi scuba tank pony size that is entitled to free fills. I tether my Marauder to such a pony tank and shoot many shots. That size scuba tank is about $140.

Just my 2 cents.
