Lets get real here. A specific example:

A reasonable receiver to use to get these warnings is a cell 
phone. Our county allows you to sign up to get the warnings by 
cell phone, which I have done. Stanford University has a class, 
EE380, which I attend occasionally. It is held in the basement 
of the Gates Computer Science building, and there is no cell 
phone reception there. Is the assertion that Stanford is 
violating the law because it built a building from concrete and 
rebar? Give me a break.

Cheers - Bill
