I set up my first node after the last major Verizon outage that rendered my cell phone useless as a mobile communications device. Now, when the next outage happens, with the always-on base station that I have at home, I can bring a portable Meshtastic radio out with me, paired to my phone via Bluetooth, and retain the ability communicate wirelessly back home, or with any of the other many nodes in the extensive network here in the NYC / Hudson Valley region. I also enticed a couple of local friends to install them and we often opt to text over the mesh. I see it as a thing that is fun to play around with now, but which may become critical at some point in the future.
