Suitable for hiker's and hitchhiker's. Good for a cache & dash, you can park right next to the cache location. Suitable for small items and small trackables.

UPDATE: Many thanks to CCFwasG for pointing out this gate was in the closing scene of a 1987 movie largely filmed in Radnage featuring Colin Firth where he spends a month in the country, I had no idea when I placed the cache.
