Millions of Americans to gaze upon Monday's once-in-a-lifetime eclipse

LIVESTREAMING AND PRICE-GOUGING

Some 200 million Americans reside within a day's drive of the totality zone, and as many as 7 million, experts say, are expected to converge on towns and campgrounds along the narrow corridor for the event. Many are attending multi-day festivals featuring music, yoga and astronomy lectures.

Millions more could potentially watch in real time as the eclipse is captured by video cameras mounted on 50 high-altitude balloons and streamed online in a joint project between NASA and Montana State University. A partial eclipse will appear throughout North America.

Adding further to the excitement is the wide availability of affordable solar-safe sunglasses produced by the millions and selling so fast that suppliers were running out of stock.

The owner of one leading manufacturer reported price gouging by second-hand dealers who were buying up large supplies in and reselling them over the internet at a huge mark-up.

Not all the hoopla will unfold on dry land. Welsh pop singer Bonnie Tyler is slated to perform her 1983s hit single "Total Eclipse of the Heart" aboard a cruise liner as the vessel sails into the path of totality from Florida on Monday.

Back on the ground, forest rangers, police and city managers in the total eclipse zone are bracing for a crush of travelers they fear will cause epic traffic jams and heighten wildfire hazards.

"Imagine 20 Woodstock festivals occurring simultaneously across the nation," Michael Zeiler, an AAS advisory panel member wrote on his website, GreatAmericanEclipse.com, referring to the famously chaotic 1969 outdoor rock extravaganza in upstate New York.

Zeiler, an avowed "eclipse chaser" who made the 650-mile (1,046 km) drive from his New Mexico home to Wyoming for a choice view, said South Carolina is likely to see the greatest influx as the destination state closest to the entire U.S. Eastern seaboard.

Monday's event will be the first total solar eclipse spanning the entire continental United States since 1918 and the first visible anywhere in the Lower 48 states in 38 years.

The next one over North America is due in just seven years, in April 2024.
