I made really good money snorkin around fishing holes and harvesting lures (and the occasional wallet). Sold them generally at half price at the local farmers market - Probably to the same good ol boys that lost em in the first place.
Best day ever= I found a duck boat and motor, still strapped to a trailer, a bunch of boat gear with a waterproof bag full of stuff, a trolling motor that worked fine once dry, three fishing poles with reels, two packed-full tackle boxes, two hundred bucks, and a cooler full of beer. That's a really good day snorkin'.
