Is the price per day only when you are out, or do you have to pay for it all year long?

Although it is not needed in many places, if it were to give you peace of mind and in a real medical situation, if the cost factor were eliminated, it might make you a bit more inclined to actually call for help. I know that some of us are very reluctant to call for help for fear of being charged or called a "sissy". I suspect that as more people use PBL's and if the current rescue units get overwhelmed there will be a time when free resuce may be reduced.
