In New York City, some bike (36) riders have formed a group called Bike for a Better City. They (37) claim that if more people rode bicycles to work there would be fewer automobiles in the downtown (38) section of the city and therefore less dirty air from car (39) engines.

　　For several years this group has been trying to get the city (40) government to help bicycle riders. For example, they want the city to paint (41) special lanes for bicycles only on some of the (42) main streets, because when bicycle riders must use the same lanes as cars, there may be (43) accidents. Bike for a Better City feels that if there were special lanes, more people would use bikes.

　　But no bicycle lanes have been painted yet. Not everyone thinks it is a good idea. (44) Taxi drivers fear that it will slow traffic. Some shop owners say if there is less traffic, (45) they'll have less business. And most people live too far from downtown to travel by bike.

　　The city government has not yet decided what to do. It wants to keep everyone happy. On weekends, the roads in Central Park may be used by bicycles only. Bike for a Better City (46) keeps fighting to get bicycle lanes downtown. Until that happens, the safest place to bicycle may be in the park.
