Last week, we went with friends to Rail Explorers in Portsmouth Rhode Island. They give you the opportunity to pedal quadricycles along closed rail tracks. They have locations in three states. Rhode Island is the closest and also offers ocean views along part of the trail. After three miles, you stop and get out for a break. While you do, the staff uses a hydraulic turntable to turn the quadricycles around for your journey back. Of course, the tracks were all decorated for Halloween.
