Sounds like you had a high voltage experience in the tetons Mike, glad to see you alive and kicking.
One thing's for sure, you will probably never get horses off the PCT so forget about it. That's a long-standing tradition. Other trails, maybe. At least in Oregon, there are programs to take disabled people into the Three Sisters Wilderness and stuff on horses. I think that's pretty cool. But I have to agree about the manure, especially when you find it right in the middle of a spring in an alpine meadow.
