When dealing with geese blocking the MUP, you need to use language they understand.
Geese don't understand most human-made noises, so yelling or ringing your bell doesn't help. Nor does a loud freehub. Those noises just aren't in either their vocabulary, or their dictionary.
If you've ever been charged by an angry goose, you know they hiss. Not Sssss like a snake, but an open-beaked Hahhhhhh. Hiss at them like that and they scatter quickly.
I tried this last night, it more or less worked. 3 different group of geese on the trail. None would have normally required stopping or more effort than altering course slightly. Two groups had begun to move, but sedately, at my approach, and both these groups stepped up the pace _a lot_ when I hissed at them. The third group (which was really one goose, the rest were off the trail) did not move at my approach, and did not move at my hiss. He just hissed back and ducked his head, without moving.
Perhaps I should try the other approach of making friends with them.
