My local dive shop hosts a end of the dive season event called Trash and Treasure. One year it was like a scavenger hunt where you receive points for bringing up items on a list. Items on the list included the everyday stuff you find like cans, cups, bottles , and rarer stuff like fishing equipment. After making my dive and finding a few items I returned to the checkout table. When I dumped my goodie bag out on the table everyone gasped in horror as the cup I found rolled out to proudly display itself. Yes it was an athletic cup.LOL
