You should be able to easily pull in and park safely next to the cache for a few moments. The roads are fairly quiet here, although you may want to keep little one's back away from the road.
Please don't drive down the small lane - It only leads to a small farm with associated houses before turning into a bridlepath. You may end up coming up against some horses.
Small container, with a logbook and pencil. No space for trackables here i'm afraid.
