The Forest Rangers was a Canadian TV series that got shown over here during the 1960's. I always associate it with Sunday evening tea as that was when it was on. The Forest Rangers was about a group of kids (the forest rangers) that lived/hung out in a fort in the middle of a forest. The rangers had a Indian guide called Joe, an old-time man of the woods type and were also friends with the Sheriff. Every week they would get involved in some adventure or other, usually with some mystery to be solved or person to be saved.
