These folks are from my area. Nice to see a happy ending. I saw a news story last night which featured the PLB involved, an ACR AquaFix. Although the story in the link below got it right, I was surprised how many media types still do not know what a PLB is. I heard the AquaFix called a "GPS locator", an "EPIRB", and just a plain old "GPS." How is the general public going to find out about what these devices can do if the local media can't figure it out. Pretty disappointing.
