Hello I'm thinking about moving some stones about 100 kg in weight for a distance of 100-200 meter to make a strong bench. No powertools and I am not worlds strongest man! Guess I could handle the weight but a stone isn't easy to secure on a backpack... how would you solve this problem? I'm thinking about some sort of sled and drag them on it on the ground. Rolling the stones on the ground would be very hard work!
