There are lots of answers to such a question, and many different contexts and meanings. I had an abrupt reminder tonight of one of the most incredible things I ever took part in. We're putting in new carpeting (no, that's not the incredible experience), so I've spent the week organizing 26 years of accumulated papers and books to clear the floors throughout the house. It's as much trouble as moving, only there's no truck to stuff everything in. I was close to finishing when I got into a cabinet that had been blocked by other boxes for literally years. There was an old photo album. I opened it and was immediately transported back to 1991 when I experienced a total eclipse of the sun at the tip of Baja California in Mexico.

The drive was quite the adventure, and if I can locate the slides and scan them, I will perhaps tell the story. But we made it, and settled in for a few days to prepare (and get sunburnt while snorkeling). We selected what appeared to be an abandoned condominium plot and set up shop.

The length of totality was going to exceed four minutes, one of the longest eclipses of the century. We had three or four telescopes with us, so Dr. Luebke could concentrate on photographing the entire event, while I and Mrs. Geotripper could work with a telescope of our own that we shared with the many people on the hillside. During totality, thirty or forty people were able to take a quick look.
At the time, we knew that the next solar eclipse that would be accessible to us would not be until August of 2017. It seemed such a long time into the distant future. I had no idea the many changes that would take place in my life, but suddenly it is upon us, on August 21. The path of totality is shown on the map below. If you have any chance at all, make your way and have a look. It is one of the most astounding sights you will ever see.
