This is a large container located in an ideal location for cache and dash visits, lots of swaps, and a Hotel for Travel Bugs and trackable items.
I advise you to park in a space as close to the hiding spot as possible, on the opposite side of the bush to the A14 (at the far rear of the car park), then use your vehicle to shield your search so you can discreetly access the cache without too much suspicion from potential muggles. The best parking spot is the corner one, near the bin, under the tree. If this space is occupied, you will need to abort. This car park can be quite busy, so please only search for the cache if you can do so without being seen.
It's always possible to access the cache from the A14 Eastbound services (Cambridge towards Bury St Edmunds). Do NOT try to access this cache from the Westbound services (Bury St Edmunds towards Cambridge). If the rear gates are open (they often are), it's usually possible to also access this cache from Heath Road (which runs between Burwell and Exning), which would allow local access without needing to drive along the A14.
Please simply remove the container from the drawstring bag. Do not try to detach the bag from it's mooring. Please replace the bag as low and deep as possible, to avoid accidental discovery. Finally, pretty please, can you seal up the plastic bag containing the log book.
