We were visiting Kent today. I had dropped my wife off at Bluewater and so had the rest of the morning to myself to do some caching. I decided to first grab a few puzzles and then these Numbers Challenges.
Wow what a lot of CCTV cameras - who is watching me I wondered. From here you get a good view of the quarry and all the building work that's going on. I was a bit nervous searching here but happily it was a quick find once I read the hint.
My profile is publicly viewable but I'll attach a screenshot anyway.
Awarding a favourite point for a good challenge and the interesting location
