If you're outside the path of totality eclipse, if there's any way you can get into the path of totality for the eclipse, do it. Take the day off. Take the kids out of school. This is a once-in-a-lifetime opportunity for most people to see a total eclipse, and it is one of the grandest sights in all of nature. It's something you'll always remember, and you'll pass stories of it onto your grandchildren.

I recommend for people, if this is the first time they're going to see an eclipse, don't get bogged down in trying to take pictures of it, because you'll spend much too much time fiddling around with cameras. Unless you've got the strength to just take a quick snapshot and let it go at that and not mess with the camera. Try to drink it in with your eyes and enjoy it.

I've seen a total eclipse from every continent - including Antarctica. And it's been a wonderful way to see the world. The eclipses take you to really unusual, off-beat places that you might not normally plan a vacation to, but they're wonderful places to go.

There's no way to oversell how spectacular and incredible seeing a total eclipse is. A lot of people think they've seen an eclipse. They think they've seen a partial solar eclipse - even if they've seen a 99 percent partial, it pales in comparison to seeing a complete, 100 percent total eclipse of the sun.

Sun is very distinct through the eclipse. You go from bright sunlight to twilight in a matter of 10 seconds. And everybody around you will start screaming like the home team just made a touchdown at the Super Bowl. It will be unmistakable when it's safe. Plus, if you're looking through the eclipse glasses, the crescent sun will get thinner and thinner and thinner, and then it will vanish. Then it's totality, and it's safe to look.

The first total eclipse that I witnessed was in 1970. I was an amateur astronomer. But after I saw the total eclipse, it couldn't be a once-in-a-lifetime experience, because it was too spectacular. I needed another eclipse fix, because I got hooked on the shadow.
