WASHINGTON (AP) — For most people, a total solar eclipse is a once-in-a-lifetime event. For some eclipse chasers, it’s a way of life.

These veteran eclipse chasers spend lots of money and craft intricate plans all to experience another mid-day darkening of the sky. Many work in science and related fields and they’ll travel around the world, even to Antarctica, to see one more.

For Monday’s full eclipse in the U.S., many of the big eclipse chasers will be in Oregon or Wyoming because there’s a better chance of clear weather there. But they’ll be ready to drive hundreds of miles to find good weather if necessary.

One couple won’t be going far this time. They’re only going as far as their driveway.

This eclipse is coming directly to them in South Carolina.
