I agree, and try to waymark parking spots when setting caches.
The reasons are as elditton says, and self evident. I did a small series south of the moor yesterday and there were no coords, and the logs were full of “I didn’t know where to park” and “Found better parking halfway round” – and I’m certain this uncertainty is one why that series has had so few visitors – I almost passed it by myself.
Also a shame; that series has been abandoned and the owners left the scene. Plenty of wet caches after this winter, but somehow it’s worse when you report it knowing it’ll never get sorted. 🙁
