Re: Only cracking I have done is
Last year I was at a conference on a Californian university campus, staying in shared dorms, the apartments of which had hotel style card door locks. Late at night, I went out to look for Perseids. As I shut the door, I realized I had the cafeteria card in my hand, not the door card. My roommates were all drinking the night away with their buddies in other rooms.
Just before resigning myself to a night on the doorstep, I thought, ok, why just try the old credit card trick. Five seconds with the nice flexible cafeteria card, and I was back in...
Can't imagine how any lock can yield to that these days!
