Outs,
I learnt that one on Unga Island, out towards Cold Bay, Alaska!
As the weather in that part of the world has to be seen to be believed....(even worse than the Shetlands if you will believe it)....I got used to hover moseying about looking between my toes or at the skid for reference until one fine day....as I flew by the Elephant ( a peculiar rock formation)....the Sea Gull mob hopped about from one foot to the other and refused to fly off.
I went back to camp for tea and stickies.
