Hitching always involves an element of risk, but it can also be one of the most rewarding ways to travel - especially if you can speak at least elementary conversational Spanish. It is getting more tricky to hitch in Argentina: some truck drivers are prohibited by company rules from picking you up; others are reluctant as it often invalidates car insurance or you become the liability of the driver. And in general, it is not advisable for women travelling on their own to hitch, or for anyone to head out of large urban areas by hitching: you're far better off catching a local bus out to an outlying service station or road checkpoint and trying from there. In the south of the country, hitching is still generally very safe. In places such as Patagonia, where roads are few and traffic sparse, you'll often find yourself part of a queue, especially in summer. Always travel with sufficient reserves of water, food, clothes and shelter: you can get stranded for days in some of the more isolated spots.
