Spread out your blanket (preferably a red, white, and blue one) and relax, wearing as much red, white, and blue as possible. Bring water and get drinks and food, listen to music, chat with your group. Sweat under the late afternoon sun.
And then when the sun sets, let the air cool a bit and take a moment to ponder. Ponder your home and how it came to be your home, and ponder your country and how it came to be and how it is.
And when you watch those fireworks spread across the sky, celebrate and be joyous. Today is the Fourth of July, Independence Day, and we're all excited together.
