Alright. John is a good 10-12 miles out east of Sun Valley, a city in Blaine County. A major landmark would be Bald Mountain, but a smaller, more magical one would be a trail of charms left buried by the local Coven. You should be able to follow the bread crumbs to John. The coven is pagan and not exactly friends of a church, don't expect the locals to be that much of a help. Sorry if this is kinda bare bones I don't know much about Idaho.
