I said I would post everything about this year.
This one is humbling!
Every morning I unlock the Bedford cart to gain access to the iPad2s. I place the lock in the exact same place. As the end of the day came yesterday, I went to lock the iPad2s. NO LOCK! I left hoping that none of the iPad2s would be missing upon my return this morning. Fortunately, the iPad2s were still present, but the lock was not.
I proceeded to find the lock and the video explains it all!
