When I stumbled into a church on the outskirts of Las Vegas one Sunday morning in 2007, I was shackled with my own heavy burden of sorts. I had $80,000 in cash hidden on my person. It was crammed into pockets, stuffed into socks and strapped beneath my clothes. The pastor was just getting his sermon fired up when I slipped into a back row with all the grace of a stiff-limbed Frankenstein.

So much for going unnoticed.
