Just purchased a Weather Radio with S.A.M.E.; need help

If you are just going to be in one place (not move around) you only really need to program the radio for the place/county you are in...

But, if you plan on driving on down the road through many different counties, then you can pre-program the radio for up to 23 different counties that you will be driving through...takes some pre planning.

At least that's the way I understand how it works.
