A great article from K0LWC about a hiker on the Long Trail in Vermont who was able to use his handheld Ham Radio to call for help after becoming ill in a mountainous region that lacked cell phone coverage. A good story that show the importance of having communications when in the backcountry.
If you are a Ham Radio Operator, always remember to take a radio with you on your outings, along with a list of the local repeaters for the area you will be in.
Remember the Wilderness Protocol as part of your backcountry adventures.
