It could be dangerous. I prefer public transit, or a taxi sometimes, but they charge too much. -_-
Keep in mind a lot of people don't take hitchhikers, but if you do choose to hitchhike, have some form of weapon available, like mace or pepper spray, just keep it in a hidden location, like a pocket, because if it's in like a purse, they could steal that, and use the spray against you. Just be careful!
