Arlington may not be the best known city in the state of Texas, but it is full of entertainment and attractions that is sure to meet any tastes or needs. It is also the largest populated city in the United States that doesn't have public transportation so you will need to rent a car to get around (and you will need a valid driver's license to do so). Taxis can get very expensive in this large city.

The weather in Arlington is typical for the southern United States. Summers are hot (climbing up near 100F) and winters are mild (rarely making it down around freezing). Fall and winter are the best times to visit the area.
