Don't count on the commercials. Some will charge you, others won't for liability reasons. One in 20 might give one person (female) in your crew a lift to the nearest spot on their way, or back to their shop, but that's about it. If you kick it out to Stone Bridge (past Hecla) you are closer to a main road and will have better luck hitching a ride back to Fishermans, but not Ruby Mountain.
"So in two seconds, away we went, a sliding down the river, and it did seem so good to be free again and all by ourselves on the big river and nobody to bother us." -Mark Twain (The Adventures of Huckleberry Finn)
