After leaving the confines of the last of the five settlements, it will take me up to six hours before I could reach the borders of the northern military camps. From that amount of travel time alone, I already know that I will struggle on finding ways to spend that time without getting bored to death. The soldiers opted to make sure that the settlements are as far from the area of the skirmishes as possible which explains the distance between the two areas.
It only took an hour of travel before I started to get really bored, even after busying myself with the mapping of the area, harvesting alchemy materials and hunting small animals of and sightseeing. The only thing I could see from both sides of my wagon were plants, stones and soil anyways. Nothing new.
This is one of the cons of travelling alone. There is just no one to talk to.
