My guess is that Jim’s boats, bikes and gear were disposed of in an estate sale or massive yard sale. I believe that his closest surviving relatives were a couple of elderly aunts and uncles.
Jim was a long time gear junkie and he didn’t buy no junk; Bell Magic, QCC 700, ICE recumbent trikes, high end hammocks, Cooke Custom Sewing tarps and etc.
If that was the case I hope that some passing gear head wandered into a yard sale and found euphoria.
