As part of our ongoing project to use as much petrol as we can, whilst it's still cheap, we took a day trip to Great Falls in Montana. This is the site of the main Lewis and Clark camp and marks the point where they left the Missouri river to continue on foot.
We skirted the bottom of the Glacier National Park, drove through Indian territory and had some time in the area.
