And then one day the inevitable happened, agents learned of the Lost Cave at the Burdock Pump ‘N’ Fill Gas Station when they stopped in and were in need of having their radiator topped off. The gas station guy had no radiator juice available, and so poured a bottle of the Lost Cave special into their radiator. Worked great. too good. And further investigation of the elixir led them to the lcation of the lost cave. But one or too tastes of the cave elixir convinced the agents that this stuff probably wasn’t alcoholic. But they sent a sample to Washington to be analyzed at a lab there to make sure. Inadvertantly, one sample made it to the dining table of one Franklin Delano Roosevelt who took a sip of it and then wanted to know what in blazes was in it.
A quick look at the paperwork showed that it was a sample of a faux brew. Franklin D decided there and then that if the people were having to resort to such desparate measures, and that there was something indeed worse than the Prohibitioned materials, that for the good of all, he got on the horn and phoned Congress and got the ball rolling to bring about an end to the Prohibition experiment.
It made a good story anyways. More likely, it had been found that by mixing the overflow from the soda fountain with water from wells near the Lost Cave, produced an ingestable, if barely, very cheap fountain drink which has been served by the Burdock Pizzia and Fine Eating to this day.
They say it is a secret recipe. But more likely, the ingredients are whatever overflows into the catch bucket.
