That was the guy I met. No-one mentions the old 'mad max' 4x4 that he uses to get most of the way out to the nets, swapping to the mud horse when it can no longer make headway.
I learnt one thing that day, if you find yourself stuck on the mud and you have to walk back to shore, don't use the high mounds of mud. They may look better, but instead walk/wade up the creeks. The water washes the mud away to firmer ground.
