In my state SAR is free unless the person was doing something really dumb. Eg. Avalanche victim = free. Vs. Hypothermia evac from winter hiking without a coat = ~$2k total.
Most of the SAR is voluntareer based here. There are several regional SAR groups all made of ordinary people who help the state in their free time. The $2k is an average not fixed amount. Depending on circumstances it'll be higher or lower.
