I am a Colorado native, but I never knew this little piece of Colorado unwritten law until today...
Never wave and yell to say hi while hiking a mountain!
According to the Summit County Rescue Group, three teams of six rescuers hit the trail with rope gear after receiving a report from another hiker who spotted two men waving and yelling from about a half-mile away.
It turns out they were just friendly Canadian hikers who were saying hello.
