I swam competitively for 14 years and have been able to swim as far as back as my memory goes and still , I hate dark bodies of water and being in open bodies of water . I get filled with dread and start having crazy anxiety if I even think about either of those things for too long . The ocean is powerful you are at it ' s mercy no matter how competent of a swimmer you may be . And screw all the shit that lives in the ocean , moving around all swiftly , waiting to eat my body made for land <| sep |> You could make the round direction be significantly more visible think rail gun from quake that is really the counter knowledge of their location <| sep |> If you ' ve got folks other than the priest who can teach , set them at it . If you don ' t , find folks with the capacity and get them trained .
