I went to my latest hunting ground on Friday just to find that the lawn contractors were running their six or so mowers over the park. Had to switch to plan B, which was a park about 15 minutes away. Found the usual clad along with a SEPTA token and this salt cap. It appears someone punched a hole in the center to use as a shaker. I never heard of Physiol Salt before so I found it interesting. Anyone ever hear of Physiol Salt?
