ILMAO! I actually do know where the keys are to my trigger locks, I just don't know which key is which. Someday when the kids aren't around, I will get the guns down and figure it out so I can hide them again and forget what I did with them.
I have mine in a safe, but access it only rarely, so I don't have the combo memorized. I have it on a piece of paper, though.
Safe storage from the average 3-year-old.
