I just locked myself up for the first time without being in (complete) control of when I would be getting back out. I put on my Curve w/ KSD-G2 (yes, the Curve is big for me, but I got it for a good price), and when I put my lock (Master Lock 4680) on, I put it into the combo-reset mode and scrambled the tumblers without looking, then locked it and scrambled the tumblers again. Now I'm fighting myself between trying out new combinations and the urge to scramble the tumblers again so I lose all track of my progress! Depending on how this goes (I have a date tomorrow night, and my girlfriend doesn't know I've been self-chastizing), I might try the same thing with this. With four tumblers, that's 10,000 posible combinations!
