the pot holes are so big in Costa Rica, at the bottom of one of them is where you would need to look for a speedster.
A few years ago, I went with my now wife and prior to flying out a friend made a suggestion (that I followed and thanked him profusely after I got back), he said to take 8 zip ties and as soon as you rent a car, make sure that you secure all of the hub caps with zip ties, because there are so many pot holes that you are bound to hit one and lose a cap. And if you know or heard anything about renting a car in CR, you know that they will charge you $400 for the hubcaps and will bill your credit card immediately too. The other suggestion... video tape the car before you leave the lot! It is the best advice I can share with anyone going down there. CR is one of the most incredible places that I have ever been and I highly suggest everyone make it there before it's natural beauty becomes concrete.
