Did you ever wonder why we enter dark holes in the ground? Could it be an instinct from our distance past, or just plain curiosity? We once lived in caves and some still do. From the distance past we find that man has always used caves. For shelter or the safety of the rock that surrounds us close like our mother’s womb. There is a strange confront that we feel when lying in a tight passage or sitting in a dark cave passage. Maybe it is because of the quietness of the place and just being able to get away from all the noise of the outside world. This book is about the experiences of many cavers and why they love the sport.
