Yeah, we've got multiple levels of backup, plus tons of simplex frequencies, HF gear, and satellite radios/phones.
30-40 years ago the "when all else fails" made some sense, but in most of the country that's not the case anymore.
Instead of ARRL focusing on the "when all else fails" thing, it would be nice if they did some articles on modern public safety radio systems and the resources that are available to those agencies. Amateur radio can still assist, but focusing their efforts in an area where help is actually needed would make more sense.
