You've guessed haven't you! The clue is in the title. I forgot to remove them, and now my stick has gone to the tip along with all the other rubbish from my street.
I stopped the lorry and asked the operatives if there was a chance it could be recovered, and was met with sniggers. Sorry, when it's gone it's gone, swallowed up, crushed to death :o(
Oh well, I have a spare, but it's not as good as the one the council gave me. Wonder if they could give me a replacement if I ask nicely?
