The question of how well traveled the area is that it really depends on where you are. There are literally hundreds of miles of old forestry and mining roads in this vast area that can see little or no traffic depending on the time of year.

The only reason we seen these people was due to us being well above them and catching a glimpse of sun reflecting off a truck window. Due to the semi-remoteness of the area, there is always a chance that there could be something wrong hence our decision to check. When we told the couple this, they were thankful that even though they were fine, that we took the time to check on them.
