Another good idea is to keep the P.OT.S. (that's plain ol' telephone service, folks) local numbers for police and medical of the town you live in and areas you ride in programed into the cell.

From your land line if you call 911 they know precisely where you are even if you can't speak (unless you have phone service on cable or VOIP).

But if I call 911 from my cell I reach highway patrol....in Sacramento....by the time they transfer me to Northern Ca Bay Area and a few more times closer and closer to the local dispatcher precious seconds can be lost.

Whether you need help or someone else does it's easy to do and could save a life.

You can find the local dispatchers number in your phone book.
