You time travel into the past to Salem Oregon during the height of the witch hunts, where you cannot leave the town. How do you build a good life with your knowledge and not be burned or hanged?

During the height of the witch hunts, Salem Oregon would have been populated by indigenous people, as it would be many years before Lewis and Clark would explore the Oregon Trail. So your best bet would be to forage off the land for survival, or try to join a tribe. Good thing you’re on the opposite coast from the witch trials, so they won’t affect you much.
