Ooooops. When it wasn't in my pocket back in the car yesterday after our walk, the only assumption was that I must have put it in Hannah's Birthday cache with the other two TBs........although i couldn't remember doing so! Pending a return visit to check later this week (if another cacher had not retrieved it by then), i logged it as such. Doh, there it was today on the floor of the car. As such , i have now "retrieved it" and will look after it carefully until i place it in another cache in the not too distant future
