I flew a charter into a grass strip on cattle station once, piper lance, five pax. Never been there before, strip was short grass with one lusher patch of grass about one third of the way down it, overflew the strip and had a good look at the general shape and width of the landing area while the owners chased some horse off the field in a landcruiser. They were eating grass from the greener bit on the strip.
Flew a circuit, touched down and slowed down. Only on the taxi back did i notice the main wheel tracks passed either side of the greener patch of grass .....which was in fact a four foot deep hole about a metre wide and filled with water. The horses were drinking out of it, not eating and the nose wheel was fortunately just off the ground until after I passed over it. I almost messed my pants when I saw it but the station owner thought I was a legend.
That could have been really unpleasant for everyone.
