I carry a small note that has emergency contact info - including someone here in town since my family is all from out of state. I also included both home and work #s for everyone just in case the accident happens during the week - during the day. I also carry my cell phone with preprogrammed numbers like "parents" "sister" "brother" etc instead of their names so if I'm ever out cold the EMTs can hopefully use the cell phone too. I don't carry Medical ID and that is a Great idea - especially here where the wrong hospital (read not-covered by my ins) could cost me a lot out-of-pocket. Just as an additional FYI - my parents also have my friends name and # here so they can reach someone locally as a "just in case".
Life should NOT be a journey to the grave with the intention of arriving safely in an attractive and well preserved body, but rather to skid in sideways, champagne in one hand, strawberries in the other, body thoroughly used up, totally worn out and screaming: "Yeah Baby! What a Ride!"
