>>2551400Fairly safe. Canadian here.
I hitchhiked the appalachian mountains from New York to Georgia. That was a great trip and most of my rides came from park rangers up and down the trail and other tourists. And did the cascade mountain from Washington state to California. Ive also hitchhiked across the midwest.
In the midwest I ran into trouble. I was robbed in Chicago and then again in Milwaukee 2 days later. Finding a ride or population center are few and far between but when I made my way into Northern WI, upper Michigan and Minnesota was it nothing but super friendly people.
The west coast was also decent until I hung out with a bunch of other homeless people in Portland OR. They ended up stealing my cooking pot, sleeping bag, and some clothing outside of Sacramento before disappering.
I would avoid huge cities if possible.
