Hey there Columbia
I really really really dont recomend you hitchhike that route, esecially by yourself. I really cant stress this enough.
From Prince George to Prince Rupert there have been dozens upon dozens of girls who have gone missing hitchhiking that route over the years. There is a huge private investigation going on into all the missing women, so I really would advise you to find another way.
For more info google or reserch "The Highway of Tears"
Good luck eh, and if your in a pinch in Prince George (where I live) give me a shout,message me on this maybe we can get a few pints or something if you have a couple pennies left over
