If you are driving yourself, I'd strongly suggest to order a great book to read: "St John Feet Fins & Four Wheel Drive" by Pam Gaffin. Search by the author's name and you should find it on Amazon and other places. About $12. Maximum speed limit on St John is 20 mph, and you drive on the left. Many hilly and curvey roads with blind curves. Some hills can be very hard if it has been raining.
