Thinking today that I think George really shined when this forum hit a lull (as now) that I really miss.
If he wasnt tied up with numero uno priority, shooting with the grandkids, you can bet there would be a 2000 word post by now on .....how to/dont do/dont even think of it...... something or other.
As always there would be stuff inserted that only a scientist would truly understand to give everyone a few 'huh??s' to chew on for a while.
At times, I honestly had to go back and read the stuff I could understand because I was too overwhelmed by the rest.
Thought I would try and throw him for a loop and started a email conversation a few years ago. Sent him this link after trying to understand what the heck these guys were talking about. Didnt have a clue.

As you can imagine I got about a billion word email back, dummied down. Couple days later a subsequent RFC post appears specifically regarding the topic of reflection and refraction. Absolutely blew me away in both knowledge and the drive to share here.
And of course, as Al stated, lotsa pictures for Marines to try to keep our attention along with a bit of trivia.
