Handling cash is something I don't do on a regular basis at all anymore. So, picking up banknotes for a trip seems fun and special. We're so "old skool", we remember the days when buying travelers' cheques was the best option. Now, however, an international network of ATM's have made that form of financial instrument obsolete.
Still, it's best to have a little bit of foreign currency in one's pocket upon arrival at an overseas destination. In the middle of next month, when we stride past the taxi drivers at the airport in Puerto Vallarta, we'll have cash for a local bus to the Centro district. If we give the driver one of these $20 peso bills for the both of us, we should get about eight pesos in return. Taking a bus costs less than US fifty cents per passenger.
