Smokies synchronous fireflies viewing June 6-13

GATLINBURG, Tenn. (AP) — It may be only love, but it's quite a show.

The Great Smoky Mountains National Park has scheduled June 6-13 as the Elkmont Firefly Viewing Event. A firefly species known as Photinus carolinus flashes synchronously to attract mates. Thousands of visitors throng the park each year to see the naturally occurring show.

Car traffic is halted at the Sugarlands Visitor Center and visitors take shuttle buses to Elkmont.

Visitors are encouraged to get tickets online through http://www.recreation.gov to guarantee parking at the visitor center without having to arrive hours early.

Each reservation costs $1.50.
