(45-48)                                                         River Taxis     In Thailand, a country full of rivers, river taxis are a good way to get around. These boats act much like buses on city streets. People wait at a boat stop, on the riverside. The boats stop to let people get on and off.      In some of Thailand’s cities, like Bangkok, street traffic can be very bad. Using a river taxi can save a lot of time. For example, many boats go up and down the Chao Phraya River in Bangkok. Many of Bangkok’s interesting sites are near the river. So, taking a boat is a great way for visitors to see that part of the city.
