In your imagination can you take yourself back to the days of the Wild West with cowboys and Indians hurtling around the dusty plains.

The Indian called out, “Wait – wagon - two miles off - drawn by two horses, one black, the other grey. Four people on board: man in a red flannel shirt, his wife, and two kids.”
