this is a relatively new website that asks you questions concerning your location and other particulars that would help 911 locate you and know more about you and your family if you need their assistance. I believe it was instituted because of that kid that got trapped in his car and they couldn't find him. Remember that? The kid died.
I did it today and it is not very threatening, they don't want info that you would want to protect, plus it is only going into a database to be used if they need to rescue either you or a family member. I think it is a good idea. It was a little slow tonight but I am sure that will improve.
Check it out and make a decision.
