Note goatherd staring at us
One of the tricks when flying there at levels to avoid being shot at (you wanted to fly low enough so that you don't get noticed until you're over them and it won't give anyone time to aim properly) was to notice the herds of goats: if they didn't start to scatter until you were over them then you were low enough! (This probably helped recruit several young goatherds to 'the other side' though.)
