When I contacted Marcus J Ranum, I didn't know what man I'll meet. I still don't know, who knows, but what I know, except I know nothing, it's I have to make simple. First because there are hundreds of crazy good photos, second because he writes enough to let you guess.
After the show, you'll want to know him better. Go and read him, check all the links and enjoy. Or not. Be your guest. It's up to you.
