Definition
A hitchhiker is someone who travels by soliciting rides from passing vehicles. They typically stand on the side of the road with a sign or outstretched thumb. It's a form of travel that relies on the kindness (or curiosity) of strangers. Hitchhiking can be an adventurous and economical way to travel, but it also carries inherent risks. Many places have laws regulating or prohibiting hitchhiking. Think of it as a gamble: you might meet interesting people or end up stranded. It is a classic trope from movies and books involving a journey.
