Off the top of my head (I probably have found stranger things)... the wellington boot just below Fish Hill, Broadway! *goes to find photo walktall uploaded of it*



The strange thing about it is the fact that it has been there unmoved for years - well, at least it was there last time I walked past 

Think I'll post more in this thread as I remember more strange things I've found/as I find strange things whilst caching in the future
