Great points.
Just thinking of MRE and water is narrow, but in my region the most likely broad critical event is total supply chain cut, so it would be a long term shelter in place situation. So I got to think for myself on that point.
For example people in Amish country aren't going to give a crap in the first place and have some of their own supply chains.
I am glad about the alert system test and think it's a great use of funds!
