I was visiting the Ashridge Mega today with my son Bobcat. This one was a "must do" because its one of the really old ones.
We reached the tree at the same time as another family. I found the cache - a little higher up than I was expecting. We had a nice chat - good to meet you Mike 987. It turned out he was on his way to set up a lab cache for this afternoon. We hadn't picked up the details for these yet so he showed us what we had to do.
Thanks for keeping this cache going all this time
