Wyoming has a lot of outdoor recreation and the SAR teams have found GMRS to be quite helpful because most people use it for group communication anyway. In case of an emergency, SAR teams can contact the victims on GMRS. Wyoming has a big push to publicize standardization of 307 (the area code for the WHOLE state) as the standard for the public to contact SAR in the field once an emergency is declared. They ask that the victims tune their GMRS/FRS to channel 3 and enter privacy code 7. The actual details are at https://hls.wyo.gov/307.
Does it works? Check out this FB link https://www.facebook.com/103003218816456/posts/135907112192733/. In truth, this case was successful and was aided by the use of GMRS, although the victims apparently weren't aware of the 307 standard.
My family and friends spend a lot of time in the back country. I always carry an Iridium GPS and, now that the state Homeland Security is encouraging use GMRS, I just got my license and a Wouxun 935G.
Have you guys seen similar standards encouraged in your states?
