Sayer, Julia, Harry, Kristie and I all went across to Windsor, Ontario to watch the 50th Annual Target Detroit Freedom Festival Fireworks. It was an absolutely spectacular 30 minute long display, and with the Detroit river in the foreground, we also saw the fireworks reflected beautifully in the water.

Just to the right of the middle plume of white in this shot, you might be able to make out the GM emblem, which is on top of the GM world headquarters, the Renaissance Center, about 73 stories high, demonstrating just how high these fireworks go up. Amazing!

If anyone gets the chance to shoot a firework display I would heartily recommend first reading
