The late 60's and early 70's found a very big 'back to earth' movement in America. Getting away from the 'rat race' was a big theme. And from this movement came the family oriented movies about the 'Wilderness Family'.
Very Disney like in thier views of nature and wild animals the movies were none-the-less fun and had great locations. Actor Robert Logan is best remembered for these films.
Just picked these up for my daughter and I to watch when we stay out at the cabin.
The family started with a small cabin, then moved into a bigger one.
