This series is prodominatly out in the rural country side. You may notice there are larger gaps where you will pass residential housing. The suggested parking for this series is down by the Village Sign where there is space for multiple cars, including the space on the green there (N52° 4.812' E000° 16.469' ... CB21 4PH ...) . There will be a short walk from there to reach cache #1. Use the Mid-Waypoint to find the public footpath.

Your Puzzle: Ozone Depletion (Wiki)
Ozone depletion and the ozone hole have generated worldwide concern over increased cancer risks and other negative effects. The ozone layer prevents most harmful UV wavelengths of ultraviolet light (UV light) from passing through the Earth's atmosphere. These wavelengths cause skin cancer, sunburn and cataracts, which were projected to increase dramatically as a result of thinning ozone, as well as harming plants and animals. These concerns led to the adoption of the Montreal Protocol in 1987, which bans the production of CFCs, halons and other ozone-depleting chemicals.
The ban came into effect in ABCD.
