Keep Out of Harm's Way
Some words of caution: Rented vehicles are identified by special license plates and stickers, which makes them an obvious target. Preventive measures can insure your safety and that of the car. When in San José, park in a parking lot and don't leave suitcases, camera equipment, jackets or anything tempting around. When out of town, ask at a hotel if the parking lot has a guard, and if not, where the safest place is to leave your car. Don't stop for anyone flagging you down on the road.
If you want the straightest, latest information , check the U.S. government travel advisories. (Just don't let it scare you off.) Yes, crime and bribery of public officials does exist here... just like at home. And to complete this don't-say-I-didn't-warn-you paragraph, I'll add that you should not attempt to buy one of the beautiful local parrots or macaws to bring home as a pet/souvenir. It's strictly illegal.
