The Windsor/Detroit border is one of the busiest international crossing points in the world. And the Detroit River separates the countries by less than a mile of natural border. Each year, the two countries celebrate a combined "Freedom Festival", which encompasses the Canadian (July 1st) and American (July 4th) Independence days.

The most famous part of the Freedom Festival is the fireworks display along the riverfront. This annual event routinely draws over 1 million people to the shoreline; a figure that comprises nearly 50% of the populations of Detroit and Windsor. This year, this spectacular light show will be simulcast on the internet, beginning at 9:00PM EDT tomorrow on this page.

This display rivals that of any other city, including New York, and the crowds are packed so close together as to be within 1/4 - 1/2 mile of the actual fireworks barges as they float in the Detroit River. Here are some pictures of last year's event.

Update:
Severe thunderstorm warnings for this area have led to the first postponement of the fireworks display in the past 20 years. The rain date is Thursday, 9:00PM EDT.
