Thanks everyone for responding!!
I put a note up on her stall door describing it, the last time and location I used it and at the end said that I probably left it somewhere and would appreciate it if everyone could keep their eyes open.
I was all alone at the barn too, so I decided to snoop through the other lockers. I never look at the other boarder's stuff unless asked to, but felt I had a right this time. Anyway...I found it hanging up in one of the teenager's lockers behind another bridle. I took down my sign and left a message for the BO to handle it.
I will be putting electrical tape on my bridle and I am debating about taking my saddle home, but since I go to the barn after work I would have to leave it in my car all day and I think that is worse.
