It's a very interesting site, and I can see how it would be helpful.
Charlie has always looked like his pit/lab background, but you are correct, something more, as well. Something that I've never been able to put my finger on, not being around him in person as you are.
You were fortunate to find that site, and I'm marking it for further reading, but also as a page that I know that I will want to revisit and share with others. Thank you!
Love All Life, Thank You For Posting! :)
