Water rolling carrier... cool idea

Here is an idea, instead of carrying water back from the watering
hole... role it. I did not read it all the way through but right off
the bat one of the things I noticed this will do is that the road to
and from the watering hole will, with time, become smooth and hard
and flat from the rolling of heavy water barrels over ti daily....
this will make the road better. Its a (possibly) unlooked for
benefit from this idea. take a look:
