can’t bail water from the boat until you first patch the leak.
what you said “No Brainer”.
I saw a U tube some place that showed Israel with pillbox placements every hundred yards armed with automatic twin 50’s on heat sensors. It showed a jack rabbit wonder across the marked zone and disappear in a blur of red.
I still think a canal cut across would be more economical. We could charge for passage and the current would be too strong to swim. It would lower the waterline around Florida and flood out Californicate at the same time. Win! Win! Win!
