I'm not sure if I've ever carried a wallet. Too long ago to remember.
Main reason is that I have a skinny ass, and a wallet looks like some sort of growth that needs surgical attention.
For many, many years I've carried my one or two credit cards, DL, NRA membership card, insurance card and the few other documents I require in the type of clear vinyl holder that comes with checkbooks. It's slim, and fits easily into a vest pocket, sport coat pocket, or suit coat pocket.
Last year I came across a guy in a checkout line who had a nice piece of leather that did all of the above. It was small and slim. It could even fit in a shirt pocket.
If I find a source for that item, and if anyone is interested, just post a reply.
