I was freediving Duluth’s amazing rock beach one afternoon, and started finding pot-smoking paraphernalia in a few feet of water just off shore. I realized I was reassembling some poor stoner’s fully stocked stash tray which he/she must have set too close to the waves. Within a relatively small radius I found pieces of two glass pipes (one largely intact), pokie tool, rolling tray, grinder, cigarette roller, and a broken glass jar. Archeological evidence of a beach culture of leisure.
