Meet the Motor City Magnet Fishers. Eight-year-old Avery Vanderwal and her father Jason can often be found fishing alongside local waterways like the Rouge and Detroit Rivers. Dressed for the job in a sparkly unicorn coat, Avery uses all of her strength to throw an unusual looking fishing line into the water: a rope tied to a heavy-duty magnet. This isn t your average fishing trip; it s magnet fishing. My favorite part about magnet fishing is getting outdoors and doing something good for the waterways, says Jason, but his daughter confesses that she loves their new pastime because of all the cool objects they find.
