There isn't technically a shortage because the government hasn't imposed any price controls. However the price has increased drastically in the past 10 years. My gas costs for scuba diving are way up.
Price increase indicates a shortage, since the purpose of a price increase is to select which sunset of consumers receive the product when not all can. Price increases are either free market rationing (a response to shortage) or a disappearance of readily accessible inputs.
That's not how shortages work. A shortage only exists when some external constraint prevents the market from clearing.
