I also carry my laminated CCL behind my DL - but both of them are behind the following picture in my wallet window.
Theory behind this:
1. Nobody sees my DL or other personal information when my wallet is open.
2. If a BG/social parasite/loser has the drop on me and opened the wallet that I've tossed to him, I tell him they are my heros - then have the chance to draw and put a bullet in him while he is being overwhelmed with warm/fuzzy feelings at the sight of his gods.
3. If it's a cop who's stopped me for any reason, I tell him/her it's my instant humor inspiration to see the pres kissing a pig - puts them in a lot better mood when I retrieve my DL and CCL behind the picture
