Not sure if this is the place to ask but thought I would give it a try. In December I was travelling with a group in a minibus from heathrow to Cardiff. We had exited the M4 and were heading into Cardiff. About 5 or 10 minutes from Cardiff we had to stop at a small lay by to answer the call of nature, ( it was dark). I remember the lay by was just before an exit, there was an over pass ahead of us and a road above the lay by. There was an overgrown grass area with small trees and bramble bushes. Anyway I was wearing an antique silver and abalone butterfly pin on my jeans and I remember snagging my leg on a bramble and of course I lost my pin but didn't realize until we got to the hotel. If someone was to find it I would appreciate having it sent to me. I really miss it. Let me know , if you decide to go treasure hunting.
