One way in which the lake culture is unique is the fishermen who row with their feet rather than arms. It seems impossible, but they somehow balance at the very tip of the boat, hold a big oar in one hand and push it around with the foot that's not balancing on the boat. It seems much harder, slower and more dangerous than traditional rowing. I guess they can see better up there while they're looking for fish, but overall it doesn't seem like a very good method.
