Caving all day
Sorry for the lack of posting on Friday. And it will be the same on Saturday. We have been underground all day surveying a cave, and will be doing it tomorrow as well. I should have time Sunday night to catch up.
Meanwhile, thanks to all the people who have generously donated or subscribed to Behind the Black. I am forever grateful for your support.
On Christmas Eve 1968 three Americans became the first humans to visit another world. What they did to celebrate was unexpected and profound, and will be remembered throughout all human history. Genesis: the Story of Apollo 8, Robert Zimmerman's classic history of humanity's first journey to another world, tells that story, and it is now available as both an ebook and an audiobook, both with a foreword by Valerie Anders and a new introduction by Robert Zimmerman.
The ebook is available everywhere for $5.99 (before discount) at amazon, or direct from my ebook publisher, ebookit. If you buy it from ebookit you don't support the big tech companies and the author gets a bigger cut much sooner.
The audiobook is also available at all these vendors, and is also free with a 30-day trial membership to Audible.
"Not simply about one mission, [Genesis] is also the history of America's quest for the moon... Zimmerman has done a masterful job of tying disparate events together into a solid account of one of America's greatest human triumphs."--San Antonio Express-News

Stupid question, maybe. But how do you arrange communication while in a cave? Is shouting good enough, or do you put some radio relays along the trail?
(There’s an attractive cave near where I live, you’ve made me interested in visiting it.)
LocalFluff: Caving is much like hiking in that you go with a group of people all traveling together. When you to need to talk to each other, you talk to each other. There is nothing about the caving environment that makes communication more difficult.
For example, if you are near a large waterfall, either underground or on the surface, communication can be hard. It doesn’t matter that much being underground. If the air is clear and quiet, communication will be easy, in both environments.
