karoocacher: I discovered today that the cache has been destroyed again. Some idiot has smashed the bottle leaving broken glass lying around. No sign of the log book or goodies. This is at least the third time it's been smashed - I assume it's the same person each time as anyone who has found this cache will attest to to fact that you certainly wouldn't stumble onto it by surprise. Hence my decision to archive it.
In a couple of months I'm leaving Birmingham so Grove Park is open if anyone wants to place a cache there.
