I've been pondering this the past couple days. Did Grok wander from place to place or did he settle down in one location/have a home-base that he always returned to after a hunt?
Talk about caves makes me think he mostly settled down in one spot, or kept relocation to a minimum throughout his life (depending on adequate food supply and danger level).
Or could he have been more like the sioux indians in South Dakota, utilizing traveling shelters (tipi's) to allow him and family/tribe to follow their food supply?
Just a random thing I'm pondering! What do you think?
