Families often celebrate Independence Day by having or going to a picnic or barbecue, and take advantage of the day off and in some years, long weekend to gather with relatives and friends. People may also do fun and relaxing hobbies like any other day off such as swimming, fishing, boating, sunbathing, playing sports, or just kicking back and relaxing. Many stores are open on the fourth so people may go shopping. In the evening, people may launch their own fireworks. Decorations (e.g., streamers, balloons, and clothing) are generally colored red, white, and blue, the colors of the American flag. Parades often are in the morning, while fireworks displays occur in the evening at such places as parks, fairgrounds, or town squares.
