I was doing some caching with my wife last Sunday and we qualified for this challenge by filling in the final two squares in our grid. Today she said she'd like to do some more so it seemed right that we should go to pick this one up.
As we approached we were a little worried that we'd be overlooked by a house, but it turned out to be ok. It took us a few minutes to find the cache. I'd actually tried four other ivy covered trees before I hit on the right one - it was further away from the footpath sign than I was expecting.
I signed the log and we left a CITO kit and took a ball. We'd noticed signs for Bignor Roman villa on our way here so we decided to pay that a visit when we got back to the car.
My stats are viewable showing that I qualify but I'll leave a screenshot anyway.
