I highly recommend spending a day in downtown. The JFK Museum is a must for everyone, IMHO. The Dallas World Aquarium is a personal favorite. I have a friend who is a curator at the Dallas Museum of Art, so I always try to stop in and see her latest exhibit. There are tons of good restaurants in the West End for a meal or drinks.
Quick Tips:
It gets really hot here in the summers, so be prepared! Lightweight, cotton clothes are a good start. Carry water with you, or buy it wherever you go, but be sure to drink plenty of it. Also, stay out of the heat between 2 and 5 pm if you can.
Our winters are usually mild, but there is often a cold 'snap' that will make you drag out the warm clothes!Best Way To Get Around:
YOU NEED A CAR! The light rail system here is wonderful, but the bus system is impossible for the uninitiated to figure out. Plus, not all cities in the area are covered by the same bus system, and you can't get from Dallas to Fort Worth, or from either city to Arlington, on the bus.
