Good evening. Welcome to the first meeting of our spring cycling season. It’s a pleasure to see so many new faces here. I certainly hope that most of you will soon feel right at home with our group and that bicycling will become a regular hobby for you and a part of your physical fitness routine. Some of you may not realize that the state of New Jersey offers ample opportunities for bicyclists of all abilities. We have rolling countryside, miles of beaches, lovely hills and valleys and thousands of miles of little-used roads. Beginners will find the shore and area south of Princeton suitable for their needs while expert riders will discover that the steep trails to the region around High Point offer a challenge to their skill and stamina. In addition, New Jersey is rich in places of historical interest. Most are carefully preserved. All have been meticulously restored. We organize tours to a variety of places nearly every weekend. Next Saturday’s tour will be a relatively easy one, from Rutgers University to the Gate Way National Park. Interested cyclists should meet at eight a.m. in the parking lot at the corner of Hamilton Street and College Avenue in New Brunswick. The minimum time for this tour is about six hours. We will use a “buddy system” throughout the ride. Each new rider should team up with a more experienced rider. If the buddies looked after each other, we can be sure that no one will be left behind on the back roads. You can pick up a map of Saturday’s tour at the information table before you leave this evening.
Questions 29 to 31 are based on the passage you have just heard.
