I have a Founders Card. It's just a little credit card sized membership card... made of aluminium. The edge is sharp. I've flown over 40 times this year and haven't been stopped even once.

I've tested TSA quite a few times and documented it all. I don't post most of it online though.. I'd hate to get it misinterpreted. ;)

I share my antics on Twitter via the #fuTSA tag.
