Also remember if DR is fairly close to base make sure they are on

Sometimes this magic number needs reconsideration. The right value may

30 or 50 miles (48 or 80.5 km). A shop located in the rural American

power for the same reason.
There was a good presentation at SHARE following Andrew in Florida. As
separation distance increases more consideration needs to placed on
staffing
and needs during force majure. Basically what they did was set-up
family
assistance center for everybody involved with DR plan even if it was
just
check the house and pick up the mail. Really well thought out,
