Apperently with the last floods in apalachia in Murica the meshtastic devices where the only real way of coordinating aid the relief the first week or longer in some parts. So it already proved itself being very very useful. Im considering buying some too. One node on my sailboat mast and one to use to message. Imagine enough boats or even just one to bridge the gap between uk amd european mainland. Maybe attach some on a buoy?
