2. Consider alternative transportation
Try the Megabus. This super-cheap bus line runs to numerous U.S. and European cities. I’ve paid as little as $1.50 to ride from New York to Philadelphia, and never more than $10.
Finally, try public transit. I use buses, subways and elevated trains whenever possible. I save a ton of money and also have the most interesting conversations with locals. (Sometimes that includes tips on which public transit lines to avoid after certain hours.)
