Not so funny at my taste. The clouds could be used as bearing aid. Just be observant to your surroundings all the time. In the ocean a solitary cloud or compact groups of them would usually stay over a distant (invisible) islands. Same on the land - above high mountain peaks below horizon or not visible in the woods. Noticing the direction of overcast clouds movement could be sufficient for a short term navigation difficulties resolution (like if you've lost bearing on some land object accidentally and have no compass).
